在低温（60 °C或更低）下，在N，N-二甲基甲酰胺（DMF）存在下，通过简单的一步处理铜箔和硫粉，在铜基底上原位合成了大面积的CuS纳米片薄膜。与以往报道的溶剂热法相比，目前的低温路线更简单，成本低，能耗低。研究了反应温度对CuS纳米片薄膜的合成及光学性能的影响。采用X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、选区电子衍射（SAED）和紫外-可见光谱仪对薄膜进行了表征。在这项研究中，我们还展示了这种方法来制备硫化铜纳米片薄膜毛玻璃和氧化铟锡玻璃（ITO）基板。我们发现在所有情况下都可以得到完美的纳米片晶体。提出了CuS纳米片基薄膜的生长机理。该方法为低温制备金属硫化物薄膜开辟了一条新的途径。
CuS nanosheet thin films with large areas were synthesized in situ on copper substrates through a facile, one-step treatment of copper foil and sulfur powder in the presence of N,N-dimethylformamide (DMF) at low temperature (60 °C or less). Compared with the previous reported solvothermal approach, the current low temperature route is simpler, low cost and low energy consumption. The effects of the reaction temperature on the synthesis and the optical property of CuS nanosheet films were investigated. The resulting CuS nanosheet films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and UV–vis spectrometer. In this study, we also demonstrated this method to prepare copper sulfide nanosheet films on ground-glass and indium tin oxide glass (ITO) substrates. We found that perfect nanosheet crystals could be obtained in all cases. The growth mechanism of CuS nanosheet-based films was proposed. The current method may open up a new way to prepare thin films of metal sulfide at low temperatures.
