Description

 This work is devoted to the production of new types of phosphors, in which due to the resonant excitation of local plasma oscillations by external light in metal nanoparticles (NPs) and the resonant exciton-plasmon interaction between plasmons in these NPs and excitons in semiconducting nanowires. Object of the study - cadmium telluride nanocrystals doped with Mn magnetic impurity, hybrid semiconductor-metal nanostructures CdTe-Au, CdTe-Ag. Purpose - Based on CdTe nanocrystals doped with Mn magnetic impurity and hybrid semiconductor-metal nanostructures to produce phosphors with substantially enhanced quantum yield. Results - The technology of synthesis of CdTe nanocrystals (NCs) doped with Mn magnetic impurity was developed to increase the light emission intensity. Developed and designed device for manufacturing hybrid semiconductor-metal nanostructures by alternately depositing films of semiconductor (CdTe) nanocrystals and metallic (Au, Ag) nanoparticles from colloidal solutions by the method of centrifugation of the subclasses Mn impurities and hybrid semiconductor-metal nanostructures produced phosphors with a substantially increased quantum radiation output. Keywords: LED, nanocrystal, quantum dot, cadmium telluride, colloidal solution, magnetic impurity, hybrid nanostructures, phosphor.
