Abstract: 

Many kind of application for metal oxide thin film now day has been discovered. Mainly come from electronics application, solar cell application, sensors, refractory, wear and corrosion-resistant coating. Titanium dioxide is promising oxide material that has useful in electrical and optical properties and also excellent transmittance of visible light [1-3]. This films synthesis by sol-gel method is particular interest because of the advantages ensured by this method [4]. The crystallization and oxide film formation effected by the thermal treatment of the modified sol-gel. Titanium tetraisopropoxide produced high hyrolysis and polycondensation rates and to precipitate into condensed particle when combined with water. Chemical modification of alkoxides with different agents is very important in sol-gel method. It can change formation of new molecular precursors that can produce a wide range of new properties.
