摘要以CuCl 2、In、CS2和NaOH为原料，以水为溶剂，在180°C下反应15 h，合成了直径为20-25 nm，长度为400-450 nm的三元CuInS 2纳米棒。采用X射线衍射、透射电子显微镜、选区电子衍射、X射线光电子能谱和紫外-可见吸收光谱等技术对产物进行了表征。实验结果表明，反应温度是影响CuInS 2纳米棒形成的重要因素，液态铟在CuInS 2纳米棒的形成过程中起着重要作用.最后，提出了溶液-液体-固体机制的纳米棒的生长。
Abstract Well-defined ternary CuInS 2 nanorods 20–25 nm in diameter and 400–450 nm in length were synthesized by the reaction of CuCl 2 , In, CS 2 , and NaOH at temperature as low as 180°C for 15 h when water was used as the solvent. The products were characterized by X-ray diffraction, transmission electron microscopy, selected area electron diffraction, X-ray photoelectron spectroscopy, and UV–vis absorption spectroscopy techniques. Experimental results indicate that reaction temperature is an important factor in this approach and liquid indium plays an important role in the formation of CuInS 2 nanorods. Finally, a solution–liquid–solid mechanism was proposed for the nanorod growth.
