Abstract
It has been found that the photostimulated luminescence (PSL) of KBr-In crystal after UV irradiation at 80 K is characterized with a complex stimulation spectrum, including 2.0, 1.8, 1.6 and 0.6 eV bands. It is proposed that the PSL is due to the optically stimulated recombination of the close defect pairs created after the decay of both lattice and near-impurity excitons. The same recombination centers are produced during the photoionization in the C absorption band.
