摘　　要：在水溶液体系和乙醇溶液体系中,于常温常压下不加入任何催化剂,用γ射线辐照技术可以成功制备出纳米ZnS晶休,其中硫代硫酸钠和二硫化碳分别为上述两体系的硫源。本工作利用XRD和TEM来分析观察纳米ZnS晶体的结构和形貌。产物具有立方体结构和球型的形貌,颗粒大小在20-50纳米之间。根据实验,提出了纳米ZnS晶体在不同体系中形成的机理。r -irradiation technique was used with success to prepare nanocrystalline zinc sulfide at room temperature and ambient pressure, without adding any kind of catalysts. Sodium thiosulfate and carbon disulfide were used as sulfur sources in water and absolute alcohol systems, respectively. Structure and morphology of the nanocrystallines ZnS have been characterized by XRD and TEM analysis. The product has a cubic structure and, morphologically, is in spherical shapes of 20 to 50 nanometers in size. Probable mechanisms of the nanocrystalline formation in different systems are proposed in accord with the experiment.
