利用溶剂热法制备纤锌矿结构ZnS:Mn^2+(1%)Fe^2+(x%)纳米线.实验结果表明:Fe^2+离子和Mn^2+离子均取代了Zn^2+离子的位置掺入到ZnS的晶格中,且Fe^2+离子在ZnS:Mn^2+(1%)纳米线中的最大掺杂浓度为15%.ZnS:Mn^2+(1%)Fe^2+(x%)纳米线的光学性质表明,纳米线具有来自于Mn^2+离子^4T1-6A1的发射峰,且随着Fe^2+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.
