Полифункциональные химические материалы и технологии. [Т. 1] : материалы Международной научной конференции, 22-25 мая 2019 г Т. 1. С. 102-104Abstract: In this work, the samples based on yttrium oxide, doped by europium ions, prepared by self-propagating high
temperature synthesis (SHTS) method and industrial method were studied. Dispersion of solid-phase samples, specific
surface and porosity of the samples were determined. Morphology and composition of the samples were determined
using SEM method. Acid-base surface state of the samples was defined by different methods. Excitation and
photoluminescence spectra of the samples were obtained. Comparison of photoluminescence intensity of the samples
synthesized by SHTS method and the change nature of the acid-base properties of these samples indicates an increase in
the intensity and basicity of Y2O3:Eu3+ surface with increasing annealing time.
