以阳极氧化铝为硬模板，采用溶剂热法制备了四元半导体Cu 2CoSnS 4单晶纳米线阵列.所制备的Cu 2CoSnS 4纳米线具有均匀的[112]生长方向。二乙烯三胺的最佳溶剂是形成单晶Cu 2CoSnS 4纳米线的关键。采用X射线粉末衍射、扫描电子显微镜、透射电子显微镜、能量色散X射线光谱和紫外/维斯光谱对所制备的Cu 2CoSnS 4纳米线的结构、形态、组成和光吸收性能进行了表征。由Cu 2CoSnS 4单晶纳米线制备的薄膜显示出清晰的光电响应，这表明其在光伏器件中具有潜在的应用前景。
Quaternary semiconductor Cu2CoSnS4single‐crystalline nanowires arrays have been prepared through a solvothermal synthetic route by using anodic aluminum oxide as a hard template. The as‐prepared Cu2CoSnS4nanowires are uniform with a [112] growth direction. An optimal solvent of diethylenetriamine is critical for the formation of single‐crystalline Cu2CoSnS4nanowires. The structure, morphology, composition, and optical absorption properties of the as‐prepared Cu2CoSnS4nanowires were characterized by using X‐ray powder diffraction, scanning electron microscopy, transmission electron microscopy, energy‐dispersive X‐ray spectroscopy, and UV/Vis spectroscopy. A thin film prepared from Cu2CoSnS4single‐crystalline nanowires displayed a clear photoelectric response, which suggested its potential application in photovoltaic devices.
