Luminescence of crystals ZnSe <Al>:Gd

Abstract

It has been experimentally shown that the luminescence spectra of ZnSe crystals doped with Gd from the vapor phase contain two mutually compatible luminescence bands. It is established that the low-energy G-band is due to recombination with association of complexes and , and the boundary B-band is the result of annihilation of excitons and interband transitions.
