| 摘 要： | 研究了ZnSe:Mn的光导激发谱.室温下观察列两个峰:4600Å和5380Å.还研究了4400Å及5200Å激发下光导与温度的关系.根据这些实验认为:Mn2+离子的第一激发态4T1,非常接近导带.理论上导出了5200Å激发下光导对温度的依赖.调节参数将理论与实验进行拟合.从选定参数中得出:Mn2+的4T1态位于导带下0.054eV.4400Å激发下光导与况度的关系用陷阱的作用解释.陷阱深度估计为0.4eV.

| Abstract: | 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. |
