Zinc oxide (ZnO) thin film was prepared by the electroless deposition method using aqueous solution of zinc acetate (Zn(CH3(00)2) as a starting material and EDTA disodium salt was employed as a complexing agent. The film was characterized for optical and morphological properties. From the results obtained, the film was found to have transmittance that increased gradually with wavelength in the VIS region of the solar spectrum, with about 0.85 (85%) at wavelength range of 600nm – 900nm. ZnO films were found to have strong absorption of about 0.75 at wavelength of 320nm that depreciates as the wavelength increased. The optical micrograph of the ZnO film illustrates the formation of submicrometer crystallites distributed more or less uniformly over the surface. The band gap of the ZnO film was found to be 3.00 eV.
