[Study on the zinc composition of cadmium zinc telluride (Cd(1 - y)Zn(y)Te) crystal by micro-photoluminescence spectra].
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.
