以阳极氧化铝（AAO）为硬模板，采用溶剂热法制备了高有序季系半导体Cu(2)ZnSnS(4)纳米线阵列。制备的纳米线是均匀的单晶纳米线。它们沿晶态[110]或[111]方向生长。采用x射线粉末衍射、透射电镜、能量色散x射线能谱、扫描电镜、紫外-可见光谱等方法对制备的Cu(2)ZnSnS(4)样品的结构、形貌、组成及光吸收性能进行了表征。提出了一种可能的纳米线阵列形成机制。在类似的机制下，我们也可以得到具有类似结构特征的Cu(2)ZnSnSe(4)纳米线阵列。
Highly ordered quaternary semiconductor Cu(2)ZnSnS(4) nanowires array have been prepared via a facile solvothermal approach using anodic aluminum oxide (AAO) as a hard template. The as-prepared nanowires are uniform and single crystalline. They grow along either the crystalline [110] or [111] direction. The structure, morphology, composition, and optical absorption properties of the as-prepared Cu(2)ZnSnS(4) samples were characterized using X-ray powder diffraction, transmission electron microscopy, energy dispersive X-ray spectrometry, scanning electron microscopy, and UV-vis spectrometry. A possible formation mechanism of the nanowire arrays is proposed. Governed by similar mechanism, we show that Cu(2)ZnSnSe(4) nanowire array with similar structural characteristics can also be obtained.
