Effect of annealing of ZnSe:Cr crystals in Bi(Zn) melt on the intensity of radiation bands of Cr ions
Abstract
The photoluminescence in visible and near-IR spectral range of ZnSe:Cr as-grown and annealed in Bi(Zn) melt crystals was investigated at room temperature. It was established that heat treatment of the crystals in Bi melt does not lead to chrome extraction, but their annealing in Zn melt results in partial extraction into melt of chrome and some other shallow impurities.
