本文以氯化铜、氯化铟、硫脲为原料,以乙二醇为溶剂,采用溶剂热法在常压下合成了片状的CuInS2(CIS) 纳米粉体.研究了合成温度、合成时间、溶液浓度对合成产物CIS物相和形貌的影响.采用涂覆工艺对粉体成膜,研究了热处理对CIS薄膜的影响.采用X射线衍射(XRD)、场发射扫描电镜(FESEM)及能谱仪(EDS)对合成产物进行了分析表征.研究结果表明:随着合成温度的升高和合成时间的延长,合成粉体的纯度提高.随着溶液浓度的增大,衍射峰出现宽化现象,合成粉体的粒径变小.在合成温度为195 ℃,保温时间为12 h,反应溶液浓度为氯化铜0.02 mol/L、氯化铟0.02 mol/L、硫脲0.04 mol/L的条件下,制备得到单一的CIS片状纳米粉体,片状颗粒的大小为200~500 nm,最终经过热处理能获厚度在5~8 μm左右的相对致密的CIS薄膜.
