Zinc oxide (ZnO) nanostructured seed layer was grown by successive ionic layer adsorption and reaction (SILAR) method on glass substrate. The as-prepared nanostructured seed layer was characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM) for its structure and surface morphology. XRD results showed a ZnO seed layer growth oriented along the (100) direction. Study of surface morphology showed ZnO nanocrystal clusters with hexagonal shape. ZnO nanorods (NRs) have been grown over the as-prepared ZnO nanostructured seed layer by immersing seed layer substrate in a chemical bath. It has been found that the morphology of the nanostructured seed layer is a key influencing factor for the growth of vertical ZnO NRs. In our growth method, we were successful in growing vertical NRs with diameter of about 100–240[Formula: see text]nm with perfect hexagonal shape. The transmittance studies were carried out to analyze the optical bandgap of the as-grown ZnO nanorods.
