Photoconductivity (PC) excitation spectrum of ZnSe:Mn has been studied. At room temperature it is different from the PC excitation spectrum of ZnSe without Mn. There are two peaks in ZnSe:Mn located at 4600Å and 5380Å

but in ZnSe only one peak is located at 4600Å. (see Fig.1).The two peaks of ZnSe:Mn have different temperature dependence. At 100K the peak of 5380Å gets very weak

but the peak of 4600Å nearly does not change(see Fig.2).The temperature dependence of PC under 4400Å and 5200Å excitation respectively has been studied.
