Abstract

A comparative study has been carried out of the composition and the reflection and luminescence spectra of yttrium aluminum garnet and sialons as promising photophosphors. It is shown that the phase composition and surface inhomogeneity of the sialon particles has no effect on the position of the dopant levels in the band gap of the matrix or the photoluminescence spectra. It is established that the quantum efficiency of photophosphors synthesized on a sialon base and doped with europium is comparable with that of the garnet phosphor Y <sub>3</sub>Al<sub>5</sub>O<sub>12</sub>:Ce, and this makes it possible to use them in producing LEDs with white luminescence. The strength of the crystalline structure of sialons is significantly higher, and therefore the brightness and luminescence color of the photophosphors shows little dependence on time and temperature.
