Abstract:

ZnO nanorod arrays were deposited by hydrothermal process via an aqueous solution with ammonia and Zinc nitrate as inorganic precursors, using TiO2 nanotube templates formed in HF solution by anodization method. The effect of NH3.H2O and ZnNO3 concentration on ZnO nanorods morphology and crystallinity were investigated. XRD demonstrates that ZnO nanorods are wurtzite crystal structure preferentially oriented in c-axis direction. The length and the diameter of the ZnO nanorod range from 1,1 mm to 3,4 mm and from 250 to 500 nm respectively.
