摘要: 用溶胶-凝胶法在氧化铝模板中制备了直径约为15、30、50、60nm的有序氧化锌纳米线/管阵列.用扫描电镜(SEM)、透射电镜(TEM)和X射线衍射仪(XRD)对氧化锌纳米线/管的形貌、结构以及相组成进行了分析.结果发现,纳米线的形貌依赖于氧化铝模板中孔洞的形貌,纳米线的长度受控于氧化铝模板的厚度,外径与氧化铝模板的孔径相等.通过控制溶胶的浓度以及氧化铝模板在溶胶中的浸泡时间可以制备出纳米管.

Abstract: Highly ordered zinc oxide nanowire/tube arrays were prepared by a sol-gel method in the pores of anodic alumina membranes (AAM). The morphology and crystalloid structure of zinc oxide nonawire/tube arrays were characterized by scanning electron microscope(SEM), transmission electron microscope (TEM) and X-ray diffraction (XRD). The results show that zinc oxide nonawires are very uniformly assembled and parallel to each other in the pores of the AAM template. The length and diameter of nanowires are dependen on the thickness and hole diameter of AAM. Zinc oxide nanotube arrays can be controlled by changing immersing time, temperature and concentration of the sol.

Key words: anodic alumina membrane, sol-gel, zinc oxide nanowire/tube arrays
