In the case LED to the conversion of light by phosphors ("phosphor converted LED" or pcLED) there is a need for a range of excitation and emission of phosphors used was adapted to the spectrum of emission of the semiconductor and the target fields of application in which you want to apply the LED. However, especially in the field of phosphors of the red glow on the basis of the activator Eu3+such adaptation can be achieved only with great difficulty, because there are only a few measures to offset the boundaries of the absorption of the phosphor with the Eu3+in the visible area.

Figure 2 shows the excitation spectrum and the emission material of figure 1.

Figure 3 shows the excitation spectrum and emission of the luminescent material according to the first variant implementation of the present invention with the use of (Y,Gd)-containing material of the nanoparticles in figures 1 and 2.

Example 1

Figure 1-3 refer to (Y,Gd)-containing material nanoparticles and fluorescent material using that (Y,Gd)-containing material of the nanoparticles. That (Y,Gd)-containing material of the nanoparticles used in this example is GdVO4:Eu (5%), which was prepared as follows.

GdCl3(9.5 mmol) and EuCl3(0.5 mmol) was dissolved in 375 ml of N2O. Then added NaVO450 ml at ambient temperature, which led to the formation of "milk" of the solution, which was heated to 100°C for about 30 minutes. The precipitate was collected, washed with water and acetone and dried at 60°C. the Yield amounted to 2,5162,

Figure 1 shows x-ray diffraction spectrum of the material GdVO4:Eu. You can see that the size of d50its particles is 10 nm.

Figure 2 shows the excitation spectrum (dotted line) and emission spectrum of the material of figure 1. Excitation spectrum (dotted line) exhibits a maximum of about 290-300 nm, and the emission spectrum has several sharp bands, and Napoletana band falls at 625 nm.

Material GdVO4:The Eu then suspended in ethanol and the solution was added 2-thenoyltrifluoroacetone (see structure below) and NaOMe in ethanol. The suspension was heated under reflux for one hour. After cooling, the resulting precipitate was collected and washed twice with ethanol. The output light yellow powder was 0,1075,

2-Thenoyltrifluoroacetone (FA)
