In this study, we investigate the effect of temperature and growth time on ZnO morphology. ZnO nanorods can be synthesized via electrodeposition and sol-gel method using zinc acetate and hexamethylenetetramine (HMT) or 2"‘methoxyethanol (MEA) as precursor and glass slide or FTO as a substrate. In samples deposited by sol-gel, growth time and growth temperature are fixe but in electrodeposited samples, the growth time varied from 15-60 min. The substrates with ZnO nanorods growth by sol-gel technique are annealed at different temperatures which are varied from 240 °C to 300 °C. Obtained films were characterized by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD). The result indicates that different temperature and growth time produces nanorods with different size, diameter, growth density and orientation. Structural characterization shows a preferred c-axis (002) oriented growth. Scanning Electron Microscopy (SEM) images reveals uniformly distributed hexagonal ZnO nanorods. The best aligned ZnO nanorods obtained is that grown at 60 min via electrodeposition and that annealed at 280 °C via sol-gel method.
