Abstract
The peculiarities of absorption spectra of SrLaAlO4 single crystals ar e investigated as well as the influence of thermal annealing in air an d gamma-irradiation (Co-60 source) on them. A more complex structure o f absorption bands was revealed, in contrast to previous investigation s. The investigation of changes of absorption spectra induced by annea ling and irradiation suggests that both reversible and irreversible pr ocesses take place in either case and the oxygen defects are most prob ably responsible for the observed effects.
