In this study, Zinc Oxide (ZnO) nanorod films were deposited onto tin doped indium oxide (ITO) coated glass substrates. These films were grown by electrodeposition method from an aqueous route, called chronoam-perometry. Solution temperature was kept at 90 degrees C and electrodeposition was carried out under -1 V applied voltage. The deposition time of the films was selected between 30 and 90 min at 15 min interval. The structural, morphological and optical properties of the films were investigated using X-ray diffractometer (XRD) field emission scanning electron microscope (FESEM) and UV-Vis spectrophotometer, respectively. According to XRD results, an improvement in the crystallinity of the films was observed depending on the increase in the deposition time. The surfaces coated uniformly with nanorods, which is almost perpendicular to the substrate, were observed in the FESEM micrographs. It was also observed that diameters of ZnO nanorods increased with increasing deposition time. On the other hand, the transmittance spectra of these films were measured and the absorption band edges shifted to higher wavelengths as the deposition time increased.
