Deposited Films

Titania thin films were prepared by electrophoretic deposition at various deposition times (1, 5 and 10 min) in constant applied potential (5 V). For this purpose, modified titania sol was prepared as a colloidal suspension. The influence of deposition time on the thickness and optical properties of titania films was investigated. Scanning electron microscope images illustrate compact and homogeneous titania films deposited on FTO substrates. The results show that the film thickness increases with increasing the deposition time. It could be inferred from UV-Vis spectroscopy that increasing the thickness of deposited film causes higher absorbance at UV region. Also, increasing the deposition time from 1 to 5 min leads to increase in optical band gap of the deposited films.

Optical properties of titania thin films supported on silica plates and compounded with varying amounts of Co(II) from cobalt nitrate are reported. The ellipsometric characterization allows to model the spatial micro-structure of these thin film composites. The titania films were produced by the sol-gel method at room temperature and their thicknesses can be controlled by modifying the experimental conditions. The refractive index of the doped titania films was also determined by using ellipsometry.
