Abstract
The relaxation of photodarkening in amorphous As-Se films doped by Sn, Mn, Sm and Dy was investigated. The addition of metals diminishes the photodarkening effect and the thermal photobleaching effect, especially in the case of dysprosium modifier. Metal doping contributes to the stabilization of glassy matrix with respect to light exposure and thermal treatment
