A simple sol-gel method was applied to prepare high refractive index thin film used in antilaser optical area. The method composed of two steps employing a complete hydrolysis and a restrained polycondensation at low temperature. The morphology of the resulting sol was determined by dynamic light scattering(DLS) techniques and was characterized as anatase by high-resolution transmission electron microscopy(HRTEM). The thin optical films were deposited on K9 glass by a sol-gel spin-coating method. The film shows the presence of nanocrystalline anatase phase by X-ray diffraction(XRD) analysis. The film surface examined by atomic force microscopy(AFM) shows a mean square roughness of 7.5 nm. The transmission spectra of the film were measured using a UV-Vis-NIR spectrometer, and the refractive
