ЛЮМИНЕСЦЕНТНЫЕ СВОЙСТВА КРИСТАЛЛОВ ZnSe, ЛЕГИРОВАННЫХ МАРГАНЦЕМ В ПРОЦЕССЕ РОСТА
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.
