| 摘 要： | 利用激光显微Raman光谱仪测量了5块碲锌镉晶片的显微荧光光谱,通过对来自碲锌镉材料带隙的荧光峰进行拟合,得出碲锌镉材料Eg值,从而可以计算出材料的Zn组分值;利用激光显微Raman光谱仪的定峰位X-Y平面扫描技术,可以便捷和无损伤地给出碲锌镉晶片的Zn组分分布图。

| Abstract: | The micro-photoluminescence of five cadmium zinc telluride crystal wafers was measured by laser excited micro-Raman (spectroscopy.) The E_g value of cadmium zinc telluride material was calculated by fitting the micro-photoluminescence peaks which came from material band gap. Then the Zn composition of cadmium zinc telluride material could be obtained. By using the spectroscopic function of X-Y scanning technique fixing the photoluminescence peak, the mapping of Zn composition could be easily and non-destructively given. |
