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
total volume of the samples. The remaining volume of samples consists of the phases $Al_2O_3$ 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.
