Abstract
In this study, we fabricated the zinc oxide (ZnO) nanorods arrays by hydrothermal technique on indium doped tin oxide (ITO) substrate with different concentration of the precursor with zinc nitrate and hexamethyleneteramine (HMTA) in distilled water. Structure, morphology and optical properties of ZnOnanorods on ITO substrate were characterized by x-ray diffractometer, field-emission scanning electron microscope and spectrophotometer, respectively. The ZnO nanorod arrays showing preferentially oriented in the (001) direction and with a wurtzite structure. The scanning electron microscopy results showed that the hexagonal shape ZnO nanorods. It was found that the diameter, length and density of the ZnO nanorods arrays were strongly influenced by the precursor concentration.
