Abstract

We present the results on photoluminescent properties for ZnSe crystals doped with Mn during growth process. The
сontent of Mn in the reactor did not exceeded of 1.14*10-3g/g. It is shown that only long-wave photoluminescence
bands exist in PL spectra under different excitation wavelengths. We suppose that Mn2+ ions are responsible for PL
bands (590, 608 and 631 nm) observed in the visible PL spectra of ZnSe:Mn crystals. The excitation mechanisms of intrashell
radiation are discussed.
