Abstract

The effect of the zinc oxide’s powder modification by ZrO2 · Y2O3 nanoparticles on the spectra of diffuse reflectance and their changes after irradiation with 100-keV protons was studied at concentrations of 1, 3, 5, 7, 10, 15, and 30 wt % and T = 650 and 800 °C. Induced absorption spectra of irradiated powders were decomposed into bands of elementary defects. The effect of temperature on the band area and a change in the total absorbance of ZnO powders during nanoparticle modification and concentration was demonstrated.
