Paper Abstract

Photoluminescent spectra of CaO, MgO oxides, doped with rare-earth ions have been studied. The stimulated by IR- light photoluminescence in these materials has discovered at room temperature for the first time. Optically stimulated luminescence in Ca(Mg)O: Eu, Sm for different concentrations of dopants after exposure to UV-radiation ((lambda) equals 250 nm) and radiation with (lambda) equals 488 nm has been investigated. The physical model to explain luminescence and stimulated luminescence mechanism is proposed. Materials on the base of alkaline-earth oxides activated by rare-earth ions are suitable for multiple rewrite of information.
