采用简单的溶剂热合成方法制备了单晶CuInS2纳米线阵列。制备的CuInS2纳米线具有均匀的生长方向[112]。采用二乙烯三胺作为最佳溶剂和较长的反应时间对单晶CuInS2纳米线的形成有重要作用。采用x射线粉末衍射、扫描电镜、透射电镜、能量色散x射线光谱法和紫外可见分光光度法对制备的CuInS2纳米线的结构、形貌、组成和光吸收性能进行了表征。提出了单晶CuInS2纳米线阵列的可能形成机制。
Single crystalline CuInS2 nanowires array have been prepared via a facile solvothermal synthetic route. The as-prepared CuInS2 nanowires are uniform with a [112] growth direction. The use of diethylenetriamine as the optimal solvent and long reaction times are found to play significant roles for the formation of single crystalline CuInS2 nanowires. The structure, morphology, composition and optical absorption properties of the as-prepared CuInS2 nanowires were characterized using X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectrometry and UV–Vis spectrophotometry. A possible formation mechanism for the single crystalline CuInS2 nanowires array is proposed.
