Laser-induced irreversible change of the carrier-recombination process in CdSXSe_1–X-doped glasses

Abstract
Laser-induced irreversible changes of luminescence intensity and lifetime have been systematically investigated in CdSxSe1–x-doped glass in order to clarify the laser-induced carrier-recombination process. These changes proceed at different rates, depending on the laser’s irradiation time, intensity, and sample temperature. A new phenomenological model for this laser-induced process is proposed in which a new recombination route for carriers is created in the trapping state by activation of a distributed potential barrier of this state.
