摘要

The photoluminescence spectra of initial ZnO powder and that modified by Al_2O_3, Al_2O_3 ? CeO_2 nanopowders are investigated in the range 360-660 nm before and after 100-keV proton irradiation. It is found that the introduction of nanoparticles causes a decrease in the UV-band intensity and a change in the luminescence bands in the visual spectrum due to V_o~+ oxygen vacancies,O_(int)~- interstitial oxygen, and V_(Zn)~-zinc vacancies. Luminescence quenching in the UV and visible spectra occurs under the effect of protons. The decomposition of the spectra into elementary defects and analysis of changes in their integrated intensity during modification and irradiation of the powders are carried out.
