Abstract
The decrease in the luminescence intensity (luminescence “fatigue”) of long-wavelength emission bands with time in CdI2-Cd (λmax = 700 nm) and CdI2-Ag (λmax = 680 nm) crystals upon exposure to light in the fundamental absorption region has been studied. The process parameters, i.e., the capture cross section σ and the fraction β of centers disappeared during interband irradiation, have been determined. The model of electronic processes has been proposed, within which experimental data have been consistently explained.
