| 摘 要： | 本文测量了Zn1-xMnxS在不同Mn浓度(0.001x=0.062,T=80K时的Zn1-xMnxS的发射谱及其衰减曲线,得到两个衰减寿命:τ1=70μs,τ2>1000μs,这表明在高Mn浓度时存在着两个弛豫过程:一个是较快的,另一个则是较慢的,根据Goede等人的实验结果可以断定较慢的过程来自孤立的Mn2-离子,那么便可以判知较快的过程是来源于Mn2-离子对.正是高Mn浓度下的Zn1-xMnxS中存在着Mn2+-Mn2+离子对,在其间有能量迁移以及它和能量受主之间的能量传递造成了该体系中的IR发射.

| Abstract: | As an important material of optoelectronic devices,many questions about the luminescence of Zn1-xMnxS had been researched clearly.The origin of additional emission bands,however,which appears in Zn1-xMnxS only at higher amount of Mn(x≥0.01)are not yet fully explained.To counter this question,the emission spectra and decay curve of Zn1-xMnxS at different concentrations of Mn(0.001
