使用阳极氧化铝（AAO）作为硬模板，通过方便的湿化学方法以可控的方式制备了排列良好的黄铜矿 CuInS(2) 一维纳米结构阵列。高度定向的 CuInS(2) 纳米管、纳米试管和纳米线阵列可以通过简单地改变反应条件来选择性生长。研究发现油胺 (OLA) 在 CuInS(2) 产品的合成和形貌控制中发挥着关键作用。利用X射线粉末衍射、透射电子显微镜、能量色散X射线光谱仪、扫描电子显微镜和紫外-可见分光光度法对所制备的样品的结构、形貌、组成和光吸收性能进行了表征。讨论了CuInS(2)阵列的形成机制。
Well-aligned arrays of chalcopyrite CuInS(2) one dimensional nanostructures have been prepared in a controllable manner via a convenient wet-chemical approach using anodic aluminium oxide (AAO) as a hard template. Highly oriented CuInS(2) nanotubes, nano test tubes and nanowires arrays can be selectively grown by simply varying reaction conditions. Oleylamine (OLA) was found to play a key role in the synthesis and morphology control of the CuInS(2) product. The structure, morphology, composition and optical absorption properties of the as-prepared samples were characterized using X-ray powder diffraction, transmission electron microscopy, energy dispersive X-ray spectrometry, scanning electron microscopy and UV-Vis spectrophotometry. The formation mechanism of the CuInS(2) arrays is discussed.
