The aim of the present study is to establish the nature of the stimulated photoluminescence (PL) under IR excitation in the electron trapping materials. Investigations of the PL spectra of sulfides and oxides of the alkali-earth metals at the room and liquid N temperatures were carried out. Oxide hosts were exposed to electron beam irradiation in order to create defect levels for subsequent trapping of electrons. The oxide-based materials were preferably investigated because of their high chemical stability and low hygroscopicity in comparison with sulphide host material. This fact should be taken into account when using the materials as a data recording medium.
