Read-out processes of stored radiation energy in LiBaF3 crystals

Full text: LiBaF3 compounds are prospective materials for detection of ionising radiation. Radiation energy is stored by creation of both several F-type electron centres and hole centres. Several dopands able to change their valence after irradiation also can be used as electron traps instead of F-type centres. Dopands usually can be used as hole centres (luminescence centres) for optical read - out of stored energy. Emission spectrum of luminescence centres should be suitable for detectors sensitivity. In this paper we present the study of photostimulated luminescence of Ce3+ and Eu2+ using F-type centres optical stimulation
