摘要
采用溶剂热法,以二乙基二硫代氨基甲酸铜和二乙基二硫代氨基甲酸铟配合物为前体,油胺为配体,合成了铜铟硫纳米粒子。研究了配体与前体的配比、反应时间、反应温度以及添加剂对产物的影响,采用XRD、SEM等测试方法对产物进行了表征。结果表明,在配体和铜的物质的量比为5∶1,180℃反应,反应时间为8 h,能够得到具有较好的粒度和晶度的铜铟硫纳米粒子。
Copper indium sulfide nanoparticles were successfully synthesized through a solvothermal method which used copper diethyldithiocarbamate trihydrate and indium diethyldithiocarbamate trihydrate as precursors, and oleylamine as capping ligands. The impact of the molar ratio of ligand to precursor, the reaction time, the reaction temperature and the additives were studied. XRD and SEM were used to characterize the as -synthesized products. The results show that the CuInS2 nanoparticles with good size and crystallinity can be synthesized with ligand to precursor ratio 5：1, 8 h reation time under 180℃.
