Abstract	Synthesis of titanium dioxide (TiO2) Thin film on three microscope glasses using solgel method has been studied intensively. The starting materials were titanium(III)chloride, Ammonium Hydroxide. The components were mixed together to form the sol. Then, at 50 heating and ageing was applied to form stable sol-gel . Every glass substrate dipping in sol-gel beaker for period time (1,3,5)min respectively, for obtaining different thickness films. To evaluate the performance of films, After annealing at 500 the crystallinity of the films was determined by using the x-ray diffractometer (XRD). The change on the surface morphology was observed using Atomic Force Microscope(AFM). Finally, Optical properties measurements Absorbance (A) and transmittance(T)) for (TiO2) films were studied by UV-Visible spectrometer. analysis on the films. It has been successfully shown that the anatase crystalline phase was observed when the TiO2 thin film was annealing at 500°C. The roughness and the crystalline size of TiO2 thin film changed with the thickness. The minimum grain size( 6.92) nm for thickness 1.2μm UV-visible studying that absorption is maximum at UV spectrum (opaque) and the transmittance is maximum at the visible spectrum
