中国科学技术大学研究开发出一种金属硫化物纳米微粉辐射合成的制备方法。据介绍 ,该制备方法的特征是将金属盐及硫源化合物溶于溶剂中 ,加入适量的表面活性剂 ,搅拌至体系混合均匀 ,置于密闭的辐照容器中 ,于电离辐射场下辐照 5 0 0 0～ 5 0 0 0 0Ｇｙ后取出 ,然后进行产物洗 University of Science and Technology of China has developed a metal sulfide nanopowder radiation synthesis of preparation methods. According to reports, the preparation method is characterized by the metal salt and the sulfur source compound is dissolved in a solvent, adding an appropriate amount of surfactant, stirring until the system is uniformly mixed, placed in a sealed container irradiated ionizing radiation field irradiation 5 0 0 0 ~ 0 0 0 0 Gy after the removal, and then washed
