Nanofilms of Zinc Oxide (ZnO) were fabricated from solutions of zinc tetraoxosulphate heptahydrate, citric acid, and sodium hydroxide onto a Fluorine Tin Oxide (FTO) conductive glass by elecrodeposition process. Time as bath parameter was varied. Three samples with time interval of 30 seconds, 60 seconds and 90 seconds were fabricated. Absorbance of the films was determined with the help of spectrophotometer. Other optical properties of the nanofilms were calculated using the appropriate equations from the literature. The deposited nanofilms have high absorbance in UV region and low absorbance in VIS – NIR region. Transmittance of the nanofilms is low in UV region and high in VIS – NIR region. Reflectance of the films is low throughout the UV – VIS – NIR regions. The optimal optical thickness of 270 nm was obtained at 90 seconds. The bandgap of the nanofilms obtained is between 3.30 to 3.60 eV. Average crystallite size of 43.04 nm was obtained for the deposited ZnO thin film.
