Abstract The micro-photoluminescence of five cadmium zinc telluride crystal wafers was measured by laser excited micro-Raman spectroscopy.The Eg 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.
