本文利用溶剂热法制备了Mn掺杂的ZnS纳米线。探讨了Mn的掺杂量(5%,10%,15%)对ZnS纳米棒的尺寸、结构以及发光性能的影响,并且将所得到的纳米棒应用于聚合物环氧树脂(EP)中,制备了具有发光效应的高分子/纳米棒薄膜。X射线衍射(XRD)、扫描电镜(SEM)、能量色散光谱(EDS)进行纳米棒的形貌和组成进行了分析。荧光分析ZnS:Mn以及EP/ZnS:Mn发光性质。将ZnS:Mn纳米棒分散到环氧树脂中,在同一激发波长391 nm下,分散在EP/ZnS:Mn比ZnS:Mn纳米棒的荧光强度低,且发射波长发声蓝移。

In this article, Mn-doped ZnS nanorods synthesized via a solvent-soluble route, the effect of Mn-doped amount （5 %, 10 % and 15 %） on ZnS： Mn nanorods of its size was discussed, photoluminescence （PL）, scanning electron microscopy with energy dispersive X-ray（SEM-EDX） and X-ray diffraction （XRD） were used to characterize the structure and luminescence properties ofZnS： Mn and ZnS： Mn filled epoxy resin （EP） film. The results show that ZnS： Mn nanorods with a diameter of about 30 nm were successful synthesized when the Mn was doped by 5 mol%. ZnS： Mn has same crystalline form as ZnS nanorods. When the ZnS： Mn nanorods were added into EP, showed the The maximum intensity of emission peak achieved the at 440 nm and 459 nm respectively, while the maximum intensity of emission peak is 459 nm for pure ZnS： Mn nanorods. In addition the intensity of luminescent of the EP/ZnS：Mn is less than that of the ZnS：Mn.
