Abstract
The regularities of changes in the diffusion reflection spectra of unheated and heated ZnO powders in the range of 0.3–2.5 μm are studied after heating at temperatures from 400 to 1000°C under 100-keV proton exposure. A shift to the long-wavelength range and an increase in the absorption-band intensity in the ultraviolet region with increasing preliminary-heating temperature are established. An explanation for the optical degradation of thermally treated ZnO powders under the action of accelerated protons is proposed. This degradation is determined by the absorption of intrinsic point defects and colloid centers.
