The photobrightening of photodarkened CdS- and CdS_xSe_<1-x>-doped glasses has been investigated with luminescence experiments. Photobrightening depends on the wavelength of laser light, and is observed in all samples investigated, when the wavelength of laser light is longer than that of the absorption edge. Photobrightening is explained by considering the reexcitation of trapped electrons in glass.
