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.
通过使用阳极氧化铝 (AAO) 作为硬模板的简便湿化学方法，以可控的方式制备了排列整齐的黄铜矿 CuInS(2) 一维纳米结构。通过简单改变反应条件，可以选择性地生长高取向的 CuInS(2) 纳米管、纳米试管和纳米线阵列。发现油胺 (OLA) 在 CuInS(2) 产物的合成和形态控制中起着关键作用。使用 X 射线粉末衍射、透射电子显微镜、能量色散 X 射线光谱、扫描电子显微镜和紫外可见分光光度计对制备的样品的结构、形态、组成和光学吸收性质进行了表征。讨论了 CuInS(2) 阵列的形成机制。
