摘　　要：我们利用溶剂热的方法,合成了ZnS以及ZnS∶Mn2+纳米粒子.并利用X射线衍射、透射电镜、光致发光等测试手段对样品的结构和光学性能进行了表征.结果表明,Mn2+以替代Zn2+的方式进入到了ZnS晶格当中,并且随着Mn2+掺杂量的增加,样品的晶粒尺寸明显减小.从PL谱图可以清楚看到黄光的发射光谱,其伴随着Mn2+离子3d壳层内部的4T1-6A1转变.By means of the solvothennal method, we prepared ZnS and ZnS ： Mn2 ＋ （3 % ） nanoparticles. The structure and optical properties of the samples were studied by X-ray diffraction （XRD）, transmission electron microscopy （TEM） and photoluminescence （PL）. The results showed that the Mn^2＋ ions were substitutionally incorporated into the ZnS host for the ZnS：Mn^2＋ （3%） nanoparticles and the size of the particles was decreased as the Mn doped-ratio increased. The yellow-orange emission was observed in PL spectra which was associated with the ^4T^1_^6A^1 transition within the 3 d shell of Mn^2＋ .
