Excition optical properties in CdZnTe/ ZnTe multiple quantum wells(MQWs) grown by mefalorganic chemical vapour deposifion (MOCVD) has been studied for the first fime. Three luminescence peaks in CdZnTe/ ZnTe MQWs are observed in photoluminescence spectrum at room temperature. The experimental results indicate that they are dueto the luminescences of cover. (n-1)heavy-hole excition and impurity in the CdZnTe / ZnTe MQWs, respectively.
