摘要
采用乙醇溶剂热法以柠檬酸铜、柠檬酸铟配合物为前体,硫脲为硫源,在160℃反应24 h,合成了灯笼球形、中空球形等多种新颖形貌的铜铟硫纳米晶,较系统地研究了前体与硫源的配比、反应物浓度、反应时间、温度以及不同的硫源对产物的形貌和尺寸的影响.采用XRD、SEM、紫外-可见光谱等对产物进行了表征,结果表明产物晶化程度高且有较强的紫外吸收.
Multifarious novel morphological patterns of Copper-Indium Sulfide micro-crystals, e. g. lantern-like spheres, hollow micro-spheres etc. have been successfully prepared with Cu-citric acid, Incitric acid precursor and thiourea as sulfur source by an ethanol solvothermal method at 160℃ for 24h. It was found that the size and morphology of the as-synthesized samples were strongly affected by the molar ratios of reactant, reactant concentration, reaction time, temperature and different sulfide source. The as-synthesized Copper-Indium Sulfide products were characterized by XRD, SEM and UVvis. The results reveal that there is a high degree of crystallization and a strong UV absorption.
