摘　　要：对Er^(3+)掺杂的ZnS在960nm激光泵浦下的上转换发光作了研究报道.结果表明ZnS:Er^(3+)在960nm激光的泵浦下具有较强的上转换发光.研究中,对Er^(3+)构成的聚集团(cluster)及Er^(3+)离子之间的相互作用对ZnS:Er^(3+)的上转换发光的影响作了讨论.In this paper, the upconversion luminescence from Er3+ doped ZnS pumped by a 960 nm laser diode was studied. The results show that ZnS:Er3+ is an efficient infrared-visible upconversion material. In our experiments, the effect of Er3+ions cluster, which comes from the aggregation of Er3+ ions, on the upconversion luminescence from ZnS : Er3+ was studied too.
