The object of research is phosphors based on NC CdTe, doped with impurities of rare earth elements (La, Er) and hybrid semiconductor-metal nanostructures (NC CdTe + Au nanoparticles). Objective - To develop and test light emitting devices of the visible range of the spectrum for use in grain breeding plants. Research results - A method of manufacturing stable phosphors based on NC CdTe doped with impurities of rare earth elements (La, Er) and hybrid semiconductor-metal nanostructures (NC CdTe + Au nanoparticles) was developed. Experimental samples of visible light emitting devices (wavelength = 550-660 nm) with remote phosphors based on CdTe NC, doped with impurities of rare earth elements and hybrid semiconductor-metal nanostructures suitable for irradiation of cereal seeds were prepared. Tests at the Institute of Forage and Agriculture of Podillya NAAS of Ukraine have shown that the most effective for improving the germination of grain crops of spring wheat variety "Pecheryanka", spring barley varieties "Svarog", "Oberig", "Barvystyj" and selection of the most productive varieties are light devices with the maximum intensity of radiation 650 nm, a bandwidth of about 10 nm. Keywords: LED, nanocrystal, cadmium telluride, colloidal solution, phosphor, rare earth elements. Product Description popup.authors Ermakov Valeriy M. Ivaskevych Lyudmyla M.
