Method of forming optically permeable image inside diamond, apparatus for realising said method (versions) and apparatus for detecting said image

FIELD: physics.

SUBSTANCE: inside a diamond, in the region free from optically impermeable irregularities, an image is formed, which consists of a given number of optically permeable elements of micrometre or submicrometer size, which are clusters of N-V centres which fluoresce in exciting radiation, wherein formation of clusters of N-V centres is carried out by performing the following operations: treating the diamond with working optical radiation focused in the focal region lying in the region of the assumed region where the cluster of N-V centres is located, while feeding working ultrashort radiation pulses which enable to form a cluster of vacancies in said focal region and which provide integral fluence in said focal region lower than threshold fluence, where there is local conversion of the diamond to graphite or another non-diamond form of carbon; annealing at least said assumed regions where clusters of N-V centres are located, which provide in said regions drift of the formed vacancies and formation of N-V centres, grouped into clusters in the same regions as the clusters of vacancies; controlling the formed image elements based on detection of fluorescence of N-V centres by exposing at least regions where image elements are located to exciting optical radiation, which enables to excite N-V centres and form a digital and/or a three-dimensional model of the formed image. Images formed in diamond crystals from clusters of N-V centres are visible to the naked eye, by a magnifying glass and any optical or electronic microscope.

EFFECT: image from a cluster of N-V centres is inside the crystal, cannot be removed by polishing and is therefore a reliable diamond signature and reliable recording of information without destroying or damaging the crystal itself.

The technical field

The present invention relates to a method of recording in diamonds information, more precisely to a method of creating diamonds inside images, which carry information for various purposes, for example, known only to a restricted circle of persons, such as codes help identify, label, identifying diamonds, in particular, to methods of creating inside diamond optically permeable image, invisible to the naked eye, using magnifying glasses and microscopes of various types, inside cut and uncut natural diamond or synthetic diamond without affecting their absorption characteristics, resulting in damage to the quality of diamonds.

Prior art

The problem of creating volumes diamonds images, for example for marking diamonds for the purpose of identification and tracking, without damaging their quality and, consequently, the cost, well known as some of the properties of diamond make creating these images is very difficult.

It is known that diamonds are optically transparent to wavelengths in the visible spectrum in the range of 400-700 nm, which diamond is a material of very high hardness, prone to splitting when a sudden mechanical stress or excessive local heating, and image tags, predpochtite is) having a form readable codes, samples, serial numbers, sequences of alphanumeric characters, to avoid unauthorized disclosure or deletion must have very small dimensions and inaccessible to mechanical and chemical influences of location and not to change the appearance and commercial value of the diamond.

There are various ways of drawing images on the surface of a faceted diamond. However, the facets of the faceted surface of the diamond is oriented in different directions, have very small dimensions and can be available for tagging and detecting if a precious stone is inserted into the mounting. In addition, the original surface of the label can be destroyed by mechanical and chemical treatment, such as polishing, etching. Therefore, the preferred especially for expensive diamonds is the creation of images of the label under the superficial layer of diamond without changing the outer surface.

The creation of two and three-dimensional images in the volume of the diamond is a promising technique for the purpose of storing information and for application in optical engineering.

Known methods of creating images in native diamonds in the form of labels, which is opaque to optical radiation, due to the development of the volume of damaged microstructures of diamond surrounding natural primes is, for example, a variety invisible to the naked eye of structural defects and impurities, most of which are nitrogen atoms, hydrogen and boron, or by introducing into the structure of the diamond impurity ions such as phosphorus, creating a detected defective area.

The known method and system for laser marking of diamonds (EN 2357870 C1; WO 2006/092035; US 7284396 B1), in which the proposed engraving authentication codes as labels in the volume of the diamond formed by exposure to localized internal defects in the volume of the diamond (the atoms of nitrogen, hydrogen, sulfur, phosphorus, Nickel, boron and others) managed by a sequence of laser pulses in the femtosecond range (from a few femtoseconds to 200 picoseconds) of the energy transferred by each laser pulse above the threshold energy required to cause permanent structural changes (damage) in a diamond crystal at the chosen laser wavelength and characteristics of focus. This radiation produces pulses focused below the surface and result in forming in places random distribution of these defects growing defective microstructures that are not transparent to optical radiation. Signs consist of non-diamond forms of carbon and is formed of several microscopic point label size several is micrometers (2-5 μm) when the distance between adjacent dot marks about 50 microns, and an array of point labels has an area of 250×250 μm, and need to detect the use of a special reader. However:

- created the dot markers are larger than the natural defects in diamond, which reduces the quality and commercial value of diamonds;

- the relative position of points in the label can be determined only by some of their geometrical set, for example, vertices of a virtual triangle based on three points, but not the image of the triangle;

authentication stone by mutual spatial arrangement in it point labels created in a raw diamond, may not be reliable after it is cut, when the position of the part of point labels with faces and with each other can be changed;

in connection with stochastic arrangement of natural defects in diamond create images that have visual and semantic, impossible.

A method of obtaining images in transparent materials (SU 329899 A), in which the latent image is created in a transparent diamond plates of size 50×50 mm and a thickness of 300 μm, carved from natural diamond crystals. On the surface of the sample was applied metal mask thickness of 50 μm, which by photolithographic was vitravene the desired image, the Le which the sample was bombarded with ions of phosphorus. In addition to the colored surface of the image appeared and internal image, and the plates were subjected to subsequent thermal annealing, in which a color image has disappeared. The formed image was thermally stable up to 1200°C, is not destroyed under the action of light, electric and magnetic fields. However, due to the high hardness of lattice depth of penetration of ions of phosphorus inside the diamond and the depth of the internal image may not be large, so a thin surface layer containing the tag can be removed by polishing or etching, and the increase in the number of impurities of phosphorus in diamond and the presence of visually distinct image affects its commercial value.

There is a method of embedding in single-crystal diamond obtained by the method of chemical deposition from the gas (vapor) phase on the diamond substrate, which surface, where the growth of diamond, essentially free from crystalline defects, manufacturing marks or identification marks (EN 2382122 C1), in which the synthesis process in the layer of synthetic diamond material is injected, at least one depireux additive chemical element from the group comprising nitrogen, boron and silicon, in the form of defect centers that emit upon excitation radiation characteristic is Lina waves. While nitrogen can be introduced into the synthetic plasma in different forms, usually N₂, NH₃air, N₂H₄and forms of production mark or identification mark in the form of a layer, in which when the respective optical excitation occurs fluorescence peaks 575 nm and/or 637 nm. This fluorescence is extinguished, essentially instantaneously upon removal of the excitation source. In this layer, containing deruosi nitrogen, can also be observed line photoluminescence at 533 nm. Preferably the trade mark or identification mark are in the form of one or more layers or regions, introduced in the diamond material in the synthesis process: for example, the form of the production marks or identification marks, such as a trademark, can represent one or more sets of characteristic layers, periodically distributed in the diamond layer, subject or synthetic precious stone. The recognition (detection) production marks or identification marks may be, for example, visually or by means of special optical devices. In the General case, it is preferable recognition directly to the naked eye of the observer, as this method allows to obtain spatial information, in particular binocular or the depths of the second information.

In addition, it is well known that the capture of impurities varies depending on sector growth, participating in this process, for example the sector growth of {111} often captures a higher concentration of impurities than the sector growth of {100}.

However, in this method of tagging grown synthetic diamonds in the diamond impose a known defect that does not improve the quality of the diamond, but because of the randomness of the placement of such defects in the diamond during its synthesis of the totality of introduced defects cannot be any image containing the specified elements.

In addition, this method is a method of growing diamond with a given tag and can't be used for marking natural diamonds or grown on other technologies of artificial diamonds.

The authors concluded that the most promising direction to create different hidden images in the volume of natural and synthetic diamonds, such as labels, is to use optically transparent defects, in particular, associated with the presence in the atmosphere of nitrogen, which is optically permeable for wavelengths in the visible spectrum and allowing after special treatment to get invisible to the naked eye, using magnifying glasses and microscopes of various types, but fluorescing when exposed to vazbu is giving radiation elements, which together can form a specified image inside of the diamond.

It is known that the main defects in the diamonds associated with the admixture of nitrogen, are:

Defect And similar diatomic dipole molecule N_S-N_Sthen there is a pair of nitrogen atoms in adjacent lattice sites;

Defect B1 - four nitrogen atom in the first coordination sphere of the vacancy;

Defect B2 vane segregation in the plane {100} belongs to the most easily detectable defects and can be directly observed in the electron microscope. This defect can only be found in natural crystals and only in combination with defects a and B1.

The defect With the easiest nitrogen defect crystal structure of diamond, which represents a single isolated nitrogen atom at the position of substitution. The concentration of nitrogen in the form of defects in natural diamonds usually does not exceed 10¹⁶cm^-3in some varieties of crystals, it reaches 10¹⁸cm^-3and more. In synthetic diamonds, as a rule, contains ~10 cm^-3of nitrogen.

Also known physical classification of types of diamonds depending on the content of the defects associated with nitrogen in a diamond crystal (Gbbi, Gnereal, Wagle and other Natural and synthetic diamonds. M.: Nauka, 1986, 221 pages; Wagle Alma is natural. The transmittance in the wavelength range of 0.2-25 μm. Table SDS gssd 36-82, M., 1983, the Publishing house of Standards):

Type Ia is the most common (up to 98%) type natural diamond containing up to 0.3 at.% of nitrogen. Depending on the form of inclusion of impurity nitrogen in type Ia highlighted several subtypes:

- IaA (Net type) in nature is extremely rare, the occurrence of impurity nitrogen in the form And defects. Can be obtained by heat treatment of diamond type Ib temperatures above C°;

- AV (Pure type B1) in nature is extremely rare, the occurrence of nitrogen in the form B1 defects;

- DRI' (Mixed type) - diamonds, in addition to containing A-defects and B1-defects and defects B2 (platelets). This type is further subdivided into "regular" with a constant ratio of B1/B2 and "irregular", where this ratio is arbitrarily;

Type Ib diamonds are the most rare (0,1%) found in nature. Diamonds of this type contains a single nitrogen atoms (defect) as the impurity substitution in an amount up to 10²⁰cm^-3and have a yellow color due to the absorption spectrum of the defect C. the Majority of synthetic diamonds grown from graphite at low temperatures or for a short time, are of this type. Diamonds that have undergone a longer growing cycle (usually larger) or synthesized is s, or annealed at temperatures above S°, defects begin to turn into defects And forming a synthetic type Ib diamond+IaA;

- Type IIa - malvestiti diamonds. Their basic classification criteria: the absence of absorption in the IR range 1500-1000 cm^-1, pronounced the fundamental absorption edge in the UV range near 225 nm. Diamonds of this type are quite rare. In some fields the proportion of type IIA diamonds does not exceed 1-2%. Concentration boundary that defines the identity of diamonds of type IIA, is very uncertain. Sometimes these diamonds are called "nitrogen-free", "pure", while the concentration of nitrogen in some of them can reach ~10¹⁷cm^-3;

Type IIb blue semiconductor diamonds. Contain less nitrogen than diamonds IIA, about 10¹⁵cm^-3. Blue color and semiconducting properties due to the boron impurity (defect) with a content of approximately 10¹⁶cm^-3.

Given the above, it can be argued that even diamonds with the lowest nitrogen content in the form of defects With about 10¹⁵cm^-3in volume 1 μm³(or 10^-12cm³) will be about 1000 defects With the nitrogen atoms in positions of substitution.

In addition, it is known that in natural diamonds are type 1A defects a and B1 transformative defects in C.

the example a method of processing natural diamond type 1a (EN 2237113 C2) at a temperature of more than 2150°C at a pressure 6,0-7,0 Gpa and subsequent irradiation of diamonds containing defects And the flow of electrons with a dose 5.10¹⁵-5.10¹⁸cm^-2when 2-4 MeV, and diamonds, with more than 800 ppm of nitrogen in the form of defects or B1, is the flow of electrons with a dose of more than 10¹⁹cm^-2leading to the formation of the crystal lattice of these diamonds isolated nitrogen atoms in positions of substitution - defects C.

It is known that contained in the diamond nitrogen atoms in positions of substitution - defects - can contact the vacancy, if any, and the diamond is at a temperature sufficient to drift vacancies within the crystal, forming a new stable defect - N-V center (N - nitrogen, V - position)with unique among all solids radiooptions properties and absorbing in the wavelength range 400-840 nm with a maximum absorption cross section at the level of 10^-16cm²(T.L.Wee, Y.K.Tzeng, C.C.Han, H.C.Chang, W.Fann, J.H.Hsu, K.M.Chen and Y.C.Yu, J.Phys.

The creation of vacancies in the diamond can be provided, for example, under the influence of the electron or ion beam or ultra-short laser pulses.

The creation of N-V centers in diamond, containing previously created vacancy can be achieved by annealing the diamond at a temperature sufficient to drift vacancies to the location of defects, for example, when the annealing diamond containing defects at a temperature of at least 1100°C in an oven under vacuum, resulting in the formation of these N-V centers (EN 2237113 C2).

By furnace annealing on the surface (polished faces) diamond can be formed a thin layer of graphite, which is not desirable for precious (jewelry) diamonds (diamonds), however, this layer can be easily removed with a soft polishing.

When excited by an intense optical emission from the N-V center's fluorescent, showing a red or yellow color, this fluorescence can be detected and its presence and characteristic fluorescence spectrum, we can conclude about the presence in diamond N-V centers.

If you have diamond donor impurities, which is, as a rule, are present in most natural and artificial diamonds, N-V center can capture an electron acquires negative charge, and to start to be well-known effect of double radiooptical resonance (DROR)to the th characteristic only of N-V centers in diamond, and by which it is possible to conclude that, this crystal is a diamond and that it contains exactly N-V centers (N.B.Manson, J.P.Harrison and M.J.Sellars.

Currently, the ability of N-V centers for fluorescence is used for detection (detection) of diamonds, in which such centers established throughout the volume of the diamond without forming any image or identification (detection) of products containing such diamonds.

There is a method of embedding in single-crystal diamond obtained by chemical vapor deposition, the production marks or identification marks (EN, 2382122, C1), in which the synthesis process in the layer of synthetic diamond material is injected layer, in which the main active dopasowywa additive is molecular nitrogen, boron hydrides or oxides of silicon. For example, in the first stage of growing diamond synthesis was performed using 200/250/4500 SMS³/s (standard cubic centimeter per second) CH₄/Ar/H₂at a pressure of 200×10²PA, at a temperature of 850°C in the absence of deruosi additives, the second stage of growth was performed under the same conditions as the first, but with add is the group of 0,8 SMS ³/s 20 ppm mn₂H₆in hydrogen (0,003 frequent./million) and with the addition of 25 SMS³/s 100 ppm million N₂in hydrogen (0,5 frequent./million), and the third stage of growth was performed under the same conditions as the first, but with the addition of 10 SMS³/N₂; hydrogen (0,2 frequent./million). The result has been crystal diamond layers containing nitrogen in the form of NV centers° and NV^-in which with a corresponding shorter-wavelength excitation occurs luminescence at a wavelength of 575 nm and 637 nm, accompanied by the electron-vibrational bands.

The combination of these radiations looks orange/red and this luminescence is terminated, essentially instantaneously upon removal of the excitation source. The centers of this type under normal conditions of observation does not make a significant change in the perceived color of the gemstone because this absorption occurs only defects in the marking layer. This layer is visible in a special artificial conditions of observation, and the observer can see, for example, by observing through a platform of stone, a large area of the layer, which emits light within the volume of the diamond. However, trade mark or identification mark represent only a layer of a certain color or combination of layers of different colors, but the image bearing balconcito information cannot be created using the described method.

In addition, this method is a method of growing diamond with a given tag and can't be used for marking natural diamond or synthetic diamond grown on other technologies.

Known for use in the methods of protection products label containing nanocrystals of diamond with the active centers, fluorescamine under the action of external radiation: N-V centers (EN 2357866 C1) or N-E8 centers (EN 2386542 C1)obtained by stimulation of the nanocrystals of diamond electron or ion beam with subsequent annealing at high temperature, which leads to the formation of N-V centers or N-E8 centers located throughout the volume of the nanocrystal arbitrarily loose. Then the nanocrystals containing the optically active centers, introducing the product, and a product of the effect of fluorescence nanocrystals with exciting optical irradiation judge the authenticity of the product.

It is known that the detection of such radiation fluorescence of N-V centers (EN 2357866 C1) can be performed in the device containing the source for optical excitation with a wavelength in the range of 500-550 nm, for example, radiation of the second harmonic laser yttrium aluminum garnet (532 nm), which activates the N-V centers and induces their fluorescence, and a photodetector, the setup is built on wavelengths in the range of 630-800 nm, which analyzes the spectral and temporal characteristics of the received signal fluorescence.

The conclusion about the presence of such labels in the product made on the basis of spectral characteristics of fluorescence corresponding to the known spectral characteristics of the fluorescence of the N-V center, and the differences of the fluorescence signal upon simultaneous excitation of a resonant microwave field and without it, indicating the presence in the product of the diamond, in which there are N-V centers.

However, the presence of nanocrystals of diamond in the product can be detected only as a fluorescent spot in the area containing the nanocrystals.

According to the invention the creation of optically permeable image as possible in the faceted, and uncut diamond having a surface, at least one pre-formed polished optically permeable space. Thus according to the invention, the image should be created in the field of diamond, free from extraneous optical inhomogeneities (inclusions, cracks, inclusions and the like).

Method of creating an optically permeable image in the volume of the diamond is further described in the implementation of it using the device according to the invention shown in figure 1. However, the method can be similarly implemented in the devices shown in Figa and 2.

The authors noted that for diamonds weighing less than 100 µg way to create optically permeable image, it is preferable to carry out with the annealing of diamond by irradiation area of the proposed location of the cluster N-V centers focused in her continuous optical radiation to education fluorescense cluster N-V centers.

Or can provide for the operation of irradiation areas of the proposed location of clusters of N-V centers working ultracar dim pulsed radiation simultaneously with the annealing operation and the operation of irradiation of stimulating rays.

In addition, the system 17 or 17A management can ensure the operation of the irradiation areas of the proposed location of clusters of N-V centers work ultrashort pulsed radiation simultaneously with the annealing operation, with the operation of irradiation of stimulating rays and operation of the registration of the fluorescence radiation.

In the authors conducted research on the implementation of the method of imaging according to the invention was selected embodiment of the method with simultaneous operations radiation workers radiation, exposure to radiation annealing and excitation and the registration operation of the fluorescence radiation of clusters N-V centers.

At the same time as working radiation 4 used the radiation of ultrashort laser pulses with duration of about 100 FS with a Central wavelength 1058±2 nm with the energy in each pulse, providing in the specified region, the total integral fluence exposure from 10^-3to 0.4 j/cm². Radiation 3 focused in the focal region 18 having dimensions in the range from 0.5 to 20.0 μm, namely 5 μm at a depth of 100 μm. As the optical radiation 6 annealing and used an optical excitation laser light with a wavelength of 532 nm and a power of from 0.5 to 100 watts. It was expected to generate an image consisting of a fluorescent El the cops image, having transverse with respect to the optical axis of the laser beam size of 5 μm at a depth of 100 microns.

At the same time to achieve the desired intensity of the fluorescence generated cluster N-V centres carried out the adjustment of the concentration of N-V centers in each created cluster N-V centers with correction total integral fluence working ultrashort laser pulses in the layout area of each specified cluster by increasing the number of pulses. However, the specialist in the field of laser technology, it must be clear that the correction of the total integral fluence can also be produced and by increasing the energy of the next pulse.

Method of creating an optically permeable images was carried out on the example of creating a flat image of the barcode cut natural diamond type 1A weight of 98 µg form, close to cubic, with the polished face 2A and does not contain extraneous optically impermeable discontinuity (inclusions, cracks, inclusions and the like). Thus irradiation of diamond work specified radiation 4, the radiation 6 annealing and excitation and registration of the radiation generated fluorescent image elements was carried out through one optically permeable pad-face 2A, the diamond was placed in the flow of the working radiation 4 in such a way that the specified area 2A was perpendicular to the direction specified working radiation 4.

The method was carried out as follows.

Diamond 2, which on the surface was previously performed polished optically transparent Playground 2A, was placed on the platform means 1 polished area 2A perpendicular to the axis of the beam from the parabolic mirror 10.

Command system 17 controls the source 5 was applied radiation 6, for example a continuous emission laser Verdi G2 firm Coherent average power of 1 W with a wavelength of 532 nm, 7 focus.

When this command system 17 controls the radiation source 3 was applied to the system 7 filing radiation of ultrashort laser pulse radiation 4 with an energy of 0.2 NJ, having a duration of about 100 FS at a wavelength of 1058±2 nm, which corresponds to fluency about 10^-3J/cm, which is much lower fluence of 0.4 j/cm²where is the transformation of diamond to graphite or other non-diamond form of carbon.

In system 7, the feed radiation 4 and 6, the radiation 4 is reflected from the dichroic mirror 8, the adaptive mirror 9, the managed system 17 controls that ensured the correction of the wave front of the radiation 4 and focused by a parabolic mirror 10 in the area 18 of the proposed placement of the picture element in diamond 2, mounted on the vehicle 1 so that the radiation 4 was directed perpendicularly to the pad 2A diamond 2, with the formation of the focal spot beams of the specified radiation 4 and 6 in the focal region 18.

The combined effect of the mirrors 9 and 10 provided the focusing of radiation 4 source 3 working optical radiation in the focal spot 18, 5 μm in diameter at a depth of 100 μm under the surface of the diamond. Radiation 6 annealing and excitation source 5, for example with a wavelength of 532 nm and an average power of 1 W, passed through the dichroic mirror 8 is reflected from the mirrors 9 and 10, focused in the same area 18 within the diamond, and radiation 4 source 3 working optical radiation. When focusing an ultrashort laser pulse (pulses) in the focal region 18 is achieved very high intensity laser radiation, the intensity of which with less intensity ~of 0.4 j/cm²in which there is a phase transition of diamond to graphite. This macroscopic damage of the crystal does not occur, but the formation of electron-hole plasma, heated, partial violation of the atomic bonds in the crystal, and, as a consequence, there are defects in the crystal lattice vacancy.

The impact of optical radiation source 5 (or 5A) with a wavelength of 532 nm and a power of from 0.5 to 100 watts in the case of the device shown in figures 1 and 2, or the annealing of diamond in a furnace at a temperature of 700-1200°C in the case of the device shown in Figa, leads to heating area 18 of focus, to the acceleration of p is ocess developments vacancies the drift already vacancies, as well as to the subsequent excitation of the N-V centers are grouped into clusters, using the device shown in figures 1, 1A and 2.

Continued exposure of the diamond above the radiation 6 for about 20 seconds before appearing in the area 18 of the proposed placement of the picture element radiation fluorescence recorded by the system 12 of the Desk, indicating that the positive result of annealing with the formation of vacancies, the creation of N-V centers and on the optical excitation of the N-V centers grouped in this area, especially in clusters of N-V centers.

During the specified time using the photodetector 15 system 12 registration of image elements, the signal of which is analyzed by the system 17 controls, controlled the level of fluorescence radiation of clusters N-V centers of the region 18, which focuses the radiation 6 source 5. The center of the fluorescence band of the N-V centers are expected at the wavelength of ~680 nm.

When during these 20 seconds, the emission of N-V centers were not registered or the level of intensity was lower than the given user, the irradiation process specified area of the proposed placement of the picture element repeated a necessary number of times, gradually increasing the energy cargoholds ultrashort pulse 1.1 times changing the transmittance of the attenuator, which is equipped with source 3 working optical radiation until they received the desired intensity of the fluorescence of N-V centers in the focal region 18. When this integral fluence of the pulses of the operating optical radiation 4 in the focal region 18, as counted by the system 17 controls based on the known pulse energy and focal spot size was no more than the value of 0.4 j/cm²where is the transformation of diamond to graphite or other non-diamond form of carbon. When you achieve the desired intensity of fluorescence in this focal area 18, the process was stopped. Thus was obtained a cluster of N-V centers with cross-sectional dimension of about 5 microns.

Once at a given point inside the diamond was formed cluster N-V centers, the system 17 controls gave the command for the vehicle 1 to move in a plane parallel to the face 2A of the diamond, in accordance with user-entered the digital model of the image. So focal plane 18 has moved to a new location inside the diamond crystal, and then repeating the above operations.

The above sequence of operations is repeated a specified number of times, resulting inside the crystal was formed in a specified image of the barcode, consisting of clusters of N-V centers ellipsoidal shape with a Popper who cnym size of about 5 μm and a longitudinal size of about 20 microns, mutually spaced to each other at distances of 5 μm along 5 parallel lengths of 50 μm, separated from each other at distances of 20, 30, 40 and 50 ám.

According to the invention a method of creating an optically permeable image was also carried out in diamonds weighing 10 mg in the apparatus shown in figure 2, which was produced by annealing of diamond containing already created jobs, not by means of laser radiation, and in the oven in a vacuum or inert atmosphere for 20 C. When the annealing in the furnace was producing heating of the entire crystal to a temperature of 700-1200°C, which resulted in a drift of vacancies on the distance, the smaller the cluster size, and to the formation of N-V centers. While the modes of the sources 3 working radiation source 5A of the exciting radiation, and the systems 7a, 12, 17A and the sequence of operations were similar to those described above modes sources 3 and 5 of radiation and systems 7, 12 and 17 of the device shown in figure 1.

Detection of the generated image produced by the effect of a fluorescence image, the previously created inside the diamond crystal cluster N-V centers, under the influence of the excitation radiation, which covered the diamond crystal 2. The device for detection according to the invention, the scheme of which is shown in Figure 3, allows you to read information of the diamond crystal.

Previously recorded the information may include analog or digital information, for example, the unique numeric code used to identify a precious diamond (unique digital signature diamond), or any other information.

The detecting device, the scheme of which is shown in Figure 3, contains the means 1 adapted to secure the crystal 2, the source 20 of the exciting radiation 21 (with shutter and attenuator), system 22 focus radiation 21.

When this irradiation diamond 2 exciting radiation 21 and registration of fluorescence can be carried out on the optical axis, located along the same axis excitation radiation 21, for example through one polished area 2A on the surface of the diamond 2 (Figure 3). In this case we use a semi-transparent dichroic mirror 23 (3)transmissive 21 excitation and reflecting radiation of fluorescence of N-V centers. However, registration of the fluorescence can be produced and at an angle to the axis of the excitation radiation 21, for example through another polished area on the surface of the diamond 2. This dichroic mirror is not used.

As a source 20 of the radiation 21 can be used in laser, led, lamp or other source of optical radiation that excites the N-V centers that are available in diamond, resulting in fluorescence of these centers. Radiation 21 excitation pulse, and n is discontinuous. For example, if the research as the excitation radiation, 21 used the optical radiation of the laser Verdi G2 firm Coherent, equipped reliever, with a wavelength of 532 nm and with a maximum average power of 7 watts.

System 24 registration allows you to record the fluorescence image elements and their arrangement, while the band-pass filter 25 and/or the spectrometer 29 make it possible to identify the range of N-V centers and select it on the background of scattered radiation 21 excitation. As a spectrometer 29 can be used spectrometer CCS175 firm Thorlabs, connected to the control system 31.

The source 20 of the exciting radiation 21, such as a laser (shutter) and the tool 1a is controlled by the control system 31.

In addition, the device for detection (Figure 3) contains a microwave generator 32, which generates the microwave wave with a frequency of 2,87±0,03 GHz, and the power of 3 W, controlled by the control system 31. When the microwave generator 32 is connected agreed with him microwave strip line 33, the supply of microwave power is ü to crystal diamond 2.

When using the device shown in figure 3, the geometrical dimensions of the investigated crystal diamond 2 and its images in different projections in advance can be pre-entered by the user into the computer system 31 controls. The initial position of the diamond crystal 2-axis excitation radiation 21 and the lens system 22 focus radiation 21 is set by the user and entered into the computer system 31 controls (installation method with reasonable accuracy obvious to a person skilled). However, it can be performed and the detection image, not previously known to the operators.

If in the field of crystal 2, which passes through the excitation radiation 21, there are inclusions, including N-V centers, fluorescing under the effect of said radiation 21, using the device shown in figure 3, the fluorescence radiation passes through the band-pass filter 25, which does not transmit scattered radiation 21, through the semi-transparent mirror 26 and then enters the system 27 of focusing the fluorescence radiation, which builds on the photosensitive area (CCD) camera 28 enlarged image of the emitting region, recorded by the system 31 of the control.

In the device shown in Figure 3, the spectrometer 29 registers range of fluorescence emitted is riscalla diamond 2 under the action of radiation excitation 21, then the spectrum of the fluorescence is analyzed by the computer systems 31 control and compared with a known reference spectrum of N-V centers, available in the control system 31. Based on this comparison, the system 31 a conclusion about the presence of clusters of N-V centers in the studied crystal.

In the device shown in Figure 3, the fluorescent image of clusters of N-V centers can be processed in the system 30 digital processing (Figure 3), and the digital data can be analyzed in the system 31 controls to determine their compliance with the relative position specified digital reference image.

In the device shown in Figure 3, if the size of the investigated crystal diamond 2 is larger than the diameter of the beam 21 of the excitation source 20, the focused system 22 focusing system 31 management delivers the commands to move funds 1a at a distance equal to the diameter of the laser beam in the direction perpendicular to the radiation beam 21 source 20, and thus the scanning of the flat area inside the diamond crystal 2.

If the analyzed crystal diamond 2 has a complicated cut, the computer system 31 management submits a command to the rotation means 1a so that the radiation beam 21 crossed the crystal surface 2 at a right angle. P and each position crystal diamond 2 camera 28 registers the fluorescent image inside the crystal clusters N-V centers, which is memorized by the control system 31. Thus, after a series of consecutive moves in the specified direction, the control system 31 is formed digital image of fluorescent clusters of N-V centers in the one planar cross-section of the crystal. Similarly receive the image of any other section.

If the user needs to obtain the three-dimensional image that is in the crystal image, for example, the marks in the three-dimensional object, the system 31 performs control turns means 1a and registers the image of the label in different perpendicular to each other of the projections, and then on their basis builds a three-dimensional digital image (digital model) label.

Also the display of fluorescent clusters of N-V centers can with the camera 28 to be displayed on the display system 31 controls and can be analyzed by an expert, who can also give commands to move and turns the means 1a.

The obtained three - or two-dimensional digital model of the location of the created clusters of N-V centers inside the crystal can then be analyzed by various mathematical methods and/or expert and compared with the reference digital model of the label.

Defects created in the image associated with inaccurate coordination focal oblasti crystal diamond can be saved by the user and may further serve as distinguishing features unique to this crystal, which allows to identify the person who earlier this label.

In addition, can be analyzed the nature of the crystal 2, which is observed fluorescent emission. For this purpose, the irradiation of the crystal microwave radiation.

The system 31 management takes the team on a consistent on and off the microwave generator 32 with a period of 0.1 s - modulates its power. If the effect of the double radiooptical resonance, characteristic only of N-V centres in diamond: under the action of the microwave field changes the intensity of the fluorescence of N-V centers in diamond crystal, the change of fluorescence intensity recorded by the camera 28 and the spectrometer 29, and then analyzed by the computer system 31 controls. When changes in the level of fluorescence, synchronous with the modulation power of the microwave field, it is necessary that the crystal is a diamond, and a conclusion about the presence of N-V centres in the diamond.

Performing these operations:

1. To determine whether the investigated crystal fluorescing under the action of pump included.

2. To determine whether the data enable clusters of N-V centers and whether this crystal ALM is zoom.

3. To determine whether formed from clusters of N-V centers the image.

5. For crystals with two or more polished edges, allowing to obtain a projection image of at least two non-parallel planes, to build a digital three-dimensional, and for other crystals - two-dimensional model of this image and record the image.

6. Analyze the specified image and to extract information from it.

During the research the authors carried out the detection of images in crystals using the above-described device for detection, shown in Figure 3, natural faceted crystals in the range of 90-98 µg of 15 free from optically impermeable discontinuity (inclusions, cracks, inclusions and the like), in which, presumably in one unknown group of them previously by the method according to the invention was created optically permeable image having a depth of placement, shape and size, is not known to the operators.

The detection image in the crystals was carried out as follows.

The spectrometer 29 recorded the fluorescence spectra in the field inside the crystal under the action of radiation excitation. Then the spectrum of the fluorescence and digital images of fluorescent cells were analyzed in the computer system 31 controls. CPA is out with a known reference spectrum of N-V centers allowed us to conclude about the presence of IgM clusters N-V centers in 10 of the investigated crystals. On the basis of digital image models were built detected fluorescent areas. Thus, 5 diamonds were obtained two-dimensional digital images of fluorescent areas in the form of strokes, consisting of clusters of N-V centers with cross-sectional dimension in this projection about 5 microns, located between them at distances of 5 µm 5 along mutually parallel lengths of 50 μm, separated from each other at distances of 20, 30, 40 and 50 μm, located at a depth of 100 μm. In other 5 diamonds received a two-dimensional digital image of fluorescent areas in the form of the letter X located from each other at a distance of 5 μm cluster N-V centers in segments with a length of 50 μm at a depth of 200 μm. The other 5 diamond fluorescence is not observed, indicating the absence of N-V centers.

System 31 controls gave the command of the sequential switching on and off the microwave generator 32 with a period of 0.1 s - modulated his power. The camera 28 and the spectrometer 29 10 diamonds, which were detected fluorescent radiation was registered with the change of fluorescence intensity, which was then analyzed by the computer system 31 controls. The effect of double radiooptical resonance, characteristic only of N-V centers in diamond, with changes in the level of fluorescence, sync is nymi with power modulation of the microwave field, allowed us to conclude that these 10 crystals are diamonds. In other 5 diamonds any radiation was absent.

Created diamond crystals as described above cluster N-V centers above image is invisible to the naked eye, a magnifying glass, as well as in any optical and electron microscopes, as the concentration of N-V centers in the cluster is relatively small, the small size of the cluster and small absorption cross section of N-V centers (~10^-16cm²). The image created from a cluster of N-V centers, located in the depths of the crystal, and therefore can not be removed by polishing. Destruction of N-V centers in diamond crystal without destruction or damage of the crystal the authors do not know. Thus, the image consisting of a cluster (clusters) N-V centers is a trusted signature diamond and reliable account information.
