Abstract

In the present work, it was attempted phosphor synthesis using powerful hard radiation fluxes. The surface, elemental composition, structure and luminescent characteristics of obtained YAG:Ce ceramics were studied. Ceramics has a heterogeneous structure. The main phase of the obtained ceramics is YAG, which makes up from 72 to 91% of the total volume of the samples. The remaining volume of samples consists of the phases Al 2 O 3 and CeO 2 . Synthesized YAG:Ce, YAGG:Ce ceramics has such characteristicof of phosphors. The state of the surface and the elemental composition of the surface of a sample of synthesized ceramics were studied using a scanning electron microscope. X-ray analysis of the synthesized ceramic samples was carried out on a diffractometer. Quantitative phase dependence was determined in the
TOPAS-4.2 program. The results of measuring the luminescence spectra measured upon excitation of the surface of the split of the samples are presented.
