在环己烷/Triton X-100/水/异丙醇W/O型微乳液体系中制备了Fe：ZnSe/ZnS核-壳纳米晶。采用X射线衍射仪（XRD）分析了产物的结构,利用透射电子显微镜（TEM）观察了产物的形貌,采用光致发光（PL）谱、紫外-可见（UV-Vis）吸收谱测试了产物的光学性能。着重研究了水与表面活性剂的摩尔比（R值）对合成产物的光学性能的影响。并对相关现象潜在的机理进行了讨论。%Fe：ZnSe/ZnS core-shell nanocrystals were synthesized by water-in-oil（W/O） microemulsions of cyclohexane/Triton X-100/water/propanol-2.The as-prepared nanocrystals were characterized by X-ray diffraction（XRD） technique,transmission electron microscopy（TEM）,photoluminescence（PL） spectroscopy,ultraviolet-visible（UV-Vis） absorption spectroscopy.The effect of molar ratio of surfactant to water（R value） on the optical properties of as-synthesized products was investigated,and the underlying mechanisms were discussed.
