Influence of Thickness on Structural and Optical Properties of Titanium Oxide Thin Layers

Many researchers have reported on obtaining TiO2 thin films, using different methods [1-7]. These extensive studies on TiO2 have been due to the importance of these films in variety of applications including low-loss, low-scatter optical coating for visible and near infrared optics [8-11] and electrical devices [12,13]. These applications have stimulated a considerable amount of activity in fabrication of dielectric films with high refractive index and low absorption. Compact thin films of TiO2 on conducting glass are used in new types of solar cells: liquid and solid dye-sensitized photo-electrochemical solar cells [14,15]. These films are also of interest for the photo-oxidation of water [16], photo-catalytisis [17], electro chromic devices [18] and other uses [19]. Due to the need of cost competitive devices in these application areas, simple and inexpensive techniques are required for film deposition and preparation.
