Abstract
Photoluminescence spectra in the range of 3.4–1.8 eV and X-ray photoelectron spectra are analyzed comparatively after the 100-keV proton and electron irradiation of ZnO micropowder and nanopowder. A blue shift of the ultraviolet (UV) luminescence band of ZnO nanoparticles compared with microparticles is established. Exposure to ionizing radiation leads to quenching of the luminescence bands of the ZnO micropowder and nanopowder, which is related to an increase in the concentration of interstitial oxygen.
