摘　　要：以CuCl2.2H2O为铜源,InCl3为铟源,硫脲（Tu）为硫源,分别以N,N二甲基甲酰胺（N,N-dimethylformamide,DMF）、乙二醇、乙醇、聚乙二醇-300为溶剂在200℃下反应12h合成花状CuInS2微晶。用X射线粉末衍射仪、X射线光电子能谱、场发射扫描电子显微镜对粉体的结构、形貌、相组分进行表征。研究表明：以DMF、乙二醇、乙醇、聚乙二醇-300为溶剂均能得到由厚度为100-200nm的纳米片组成的花状CuInS2微晶。并对其形成机理进行探讨。Copper indium sulphide products were synthesized via a mild solvothermal approach（at 200℃ for 12h）involving CuCl2·2H2O as the copper source,InCl3 as the indium source,thiourea as the sulfur source,N,N-dimethylformamide,ethylene glycol,ethanol and polyethylene glycol-300 as the reaction medium respectively.Morphology,structure,and phase constituents of the as-prepared CuInS2 products were characterized by X-ray diffraction（XRD）,X-ray photo-electron spectroscopy（XPS） and field-emission scanning electron microscopy（FESEM）.The results showed that the CuInS2 products synthesized in dimethylformamide（DMF）,ethylene glycol,ethanol and polyethylene glycol-300 respectively had flower-like morphology composed of large numbers of nanoplates and the thickness of CuInS2 nanoplates was found to vary from 100-200nm.A possible formation mechanism was put forward and discussed based on the experimental results.
