英文摘要	The photoluminescence of four epitaxial zns: te samples with te concentration from 0.5% to 3.1% was investigated at different temperature and ambient pressure. two well-known emission bands related to the isolated te-1 and te-2 pair isoelectronic centers were observed for the samples with te concentrations of 0.5% and 0.65%. for the samples with te concentrations of 1.4% and 3.1%, only was the te-2-related peak observed. the pressure behaviors of these emission bands, were studied at 15 k. the te-1 -related band has faster pressure shift to higher energy than zns band gap. on the other hand, the pressure coefficient of te-2 -related bands is smaller than that of the zns band gap. according to a koster-slater model, we found that the increase of the density bandwidth of the valence band with pressure is the main reason for the faster shift of the te-1 centers, while the relatively large difference in the pressure behavior of the te-1 and te-2 centers is mainly due to the difference in the pressure-induced enhancement of the impurity potential on te-1 and te-2 centers.
