英文摘要: With a special solvent, the mixture of ethylene glycol (EG) and triethylenetetramine (TETA), plate-like kesterite Cu2ZnSnS4 (CZTS) microparticles were successfully synthesized by a rapid and low-cost microwave-assisted method. In comparison with the traditional solution process for preparing Cu2ZnSnS4 powders, the reaction time was merely 3 minutes. The samples were charac-terized by X-ray diffraction, Raman spectroscopy, scanning electronic microscope, transmission electron microscopy and UV–vis spectrophotometer. The results showed that the kesterite Cu2ZnSnS4 microparticles have single phase and stoichiometric composition with plate-like diam-eters ranging from 300 nm to 1000 nm. The CZTS microparticles have an optical band gap of 1.5 eV, which matches well with optimal direct band gap...
中文摘要: 本文以一定比例的乙二醇(EG)和三乙烯四胺(TETA)混合物作为溶剂,通过快速、低成本的微波辅助方法成功合成了锌黄锡矿铜锌锡硫(Cu2ZnSnS4,CZTS)微粒。与传统制备Cu2ZnSnS4粉末的溶液法相比,反应时间仅为3分钟,是目前已知文献报道的最快合成速度。文中通过X射线衍射、拉曼光谱、扫描电子显微镜、透射电子显微镜和紫外可见分光光度计对样品进行表征。结果表明,锌黄锡矿铜锌锡硫微粒为纯相,其颗粒大小范围为300~1000 nm。铜锌锡硫微粒具有1.5 eV的光学带隙,其与最佳直接带隙(~1.5 eV)匹配良好。
