Abstract: Growth of zinc oxide (ZnO) nanostructure on seeded indium tin oxide (ITO) via chemical bath deposition were presented in this study. Growth time is believed to have vital role in order to control the physical (morphology), optical and structural characteristics of ZnO nanostructures. Several growth time of ZnO nanostructure were varied (1 H – 3.5 H) as the purpose to investigate its effect towards the growth of ZnO nanostructures, as well as their characteristics. In this study, the influence of growth time was determined using field emission scanning electron microscope (FESEM), ultra-violet visible spectrometer (UV-Vis) and x-ray diffraction (XRD). Based on the results obtained, morphological, optical and structural characteristics of ZnO nanostructure thin films grown at various growth time present different characteristics and properties. According to the results obtained, it is proved that growth time is a vital parameter to control the ZnO nanostructure growing process. ZnO nanostructure morphological changes significantly with the changes of the growing time process. As well as optical properties, the changes of absorbance and transmittance value influence the optical energy band gap of ZnO nanostructure in this study, which is the average value is 3.31 -3.40 eV. The structural characteristic of the ZnO nanostructure also affected significantly with the difference of growth time, where the crystallinity is improved with the longer growth time.
