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