The structural and optical properties of ZnO thin film prepared by sol gel process using spin coating technique on glass substrate was investigated. Spin coated ZnO film was dried at 300°C and then annealed at 600°C. The XRD analysis revealed single-phase ZnO with hexagonal zincite structure. The absorption edge revealed that the optical band gap energy for the film was between 3.26–3.27eV and electronic transition was direct transition type.
