以C19H42BrN为表面活性剂, 采用水热法合成了ZnS∶Mn纳米晶, 分别利用XRD、TEM、荧光光谱仪对其物相、形貌及光学性能进行了研究。结果表明: ZnS∶Mn纳米晶为闪锌矿ZnS结构, 颗粒近似球形, 平均粒径为4～8 nm。荧光光谱显示, ZnS∶Mn纳米晶的荧光发射峰强度随着Mn2+掺杂浓度和表面活性剂含量的增加而逐渐增强。

Using C19H42BrN as surfactant, ZnS∶Mn nanocrystallines were synthesized by hydrothermal method. The phase, size and luminescent properties of the nanocrystals were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and fluorescence photometer. The results show that ZnS∶Mn nanocrystals are 4～8 nm of particle size and have a cubic zinc blend crystal structure. The fluorescence spectra showed that the emission peak increased with the increment of Mn-doped concentration and the increment of surfactant.
