Abstract
Irradiation effects on emission centers were studied with photo and X-ray luminescence investigations of alkali chromate crystals. The X-rays and powerful laser irradiations were used for this investigation. The irradiation effects were found to depend on a type and structure of emission centers. In the alkali Chromate crystals complex emission centers of a molecular type are formed by two weight centers: the Chromate oxyanion and the defect. The bond between weight centers can be broken under irradiation action. As established in our experiment, some types of the emission centers can decay or transform into other types under action of irradiation.
