Paper Abstract

ZnTexSe1-x epilayers with composition x equals 0.005, 0.02 and 0.16 have been grown by low pressure-metal organic chemical vapor deposition (LP-MOCVD) method. Two bands (blue S1 and green S2) were observed in the ZnTexSe1-x epilayer with composition x equals 0.005 at room temperature (RT). With increasing composition x greater than 0.02, the S1 band disappeared and the S2 band was the main emission in photoluminescence (PL) spectra. The origin of the S1 and S2 bands was attributed to excitons trapped at Te1 and Ten (n greater than or equal to 2) cluster.
