Abstract
Transition metal (TM) ions are efficient centers of nonradiative recombination in II-VI compounds [1]. In this paper we show that twostep ionization transitions of Cr result in the appearance of the donor-acceptor pair (DAP) photoluminescences (PLs) of ZnSe:Cr. Blue DAP PL of ZnSe is observed under photoexcitation with a photon energy lower than the emission energy. Such light emission is called anti-Stokes luminescence (ASL). Even though ASL was observed previously in several media [2-4] its mechanism is still disputed.
