Description
Photo- and X-rays luminescent properties of the layered CdBr2 crystals in the temperature region of 80...500 K have been investigated. It has been found out that the most effective luminescence is excited at the temperatures 100...140 K with the ultraviolet light from the exciton absorption region of crystals (259 nm). The annihilation of excitons autolocalized on the deep acceptors causes the luminescence in the region 380 nm which is quenched completely at the temperatures above 120 K. Strong exciton-phonon and electron-phonon interactions cause the excitons destruction and recombination of nonequilibrium electron-holes pairs through the donor-acceptor (DA) complexes of intrinsic and impurity defects
