摘　　要：利用溶剂热法制备纤锌矿结构ZnS:Mn2+(1%)Fe2+(x%)纳米线.实验结果表明:Fe2+离子和Mn2+离子均取代了Zn2+离子的位置掺入到ZnS的晶格中,且Fe2+离子在ZnS:Mn2+(1%)纳米线中的最大掺杂浓度为15%.ZnS:Mn2+(1%)Fe2+(x%)纳米线的光学性质表明,纳米线具有来自于Mn2+离子4T1-6A1的发射峰,且随着Fe2+离子掺杂浓度的增加其发光强度降低.The wurtzite-type Fe/Mn co-doped ZnS nanowires were prepared by a simple solvothermal method at 180℃ without any surface-active agent. The results showed that both the Fe2＋ and Mn2＋ ions were incorporated into the ZnS host and the maximum concentration of the Fez＋ ions in the ZnS：Mn2＋ （1% ） nanowires was 15%. After adding Fe2＋ ions into the ZnS ： Mn2＋ （ 1% ） nanowires, the emission peak centered at 579 nm corresponding to theaT1-6A1 transition of Mn2＋ can be observed. As the Fe2＋ doped ratio increased,the concentration quenching effect can be observed for all the peaks.
