Fabrication and Characterization of Highly Ordered Zinc Oxide Nanowire/Tube Arrays by Sol-Gel Template Method

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 dependent 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.
