Synthesis of Ternary Compounds Cu0.8Ag1.2S and Cu0.5Ag1.5Se with High Crystallinity at Room Temperature and Characterization with XPS
【摘要】 在乙二胺溶液中室温下合成了三元化合物Cu0.8Ag1.2S和Cu0.5Ag1.5Se纳米晶。将Ag2O和Cu2O用聚甲醛还原为Ag和Cu,与单质S和Se反应得到产物。用X射线粉末衍射、透射电子显微镜、X射线光电子能谱测试技术进行了结构表征,同时对产物形成机理进行了探讨。
【Abstract】 Ternary compounds Cu0.8Ag1.2S and Cu0.5Ag1.5Se with high crystallinity were prepared at room temperature in ethylenediamine solution.The procedure included the reduction of Ag2O and Cu2O by polyformaldehyde,followed by reaction of fresh-produced Ag,Cu with S or Se.The products were characterized with X-ray powder diffraction patterns,transmission electron microscope images and X-ray photoelectron spectra.A possible formation mechanism was proposed.
