Abstract
The photobrightening of photodarkened CdS- and CdSxSe1-x-doped glasses has been investigated with luminescence experiments. Photobrightening depends o n the wavelength of laser light, and is observed in all samples investigate d, when the wavelength of laser light is longer than that of the absorption edge. Photobrightening is explained by considering the reexcitation of tra pped electrons in glass.
