A study on the optical and structural properties of transparent Tio2 thin films prepared by sol-gel method

摘要

In this research, the optical and structural properties of TiO2 thin film were studied. The films were made by dipcoating technique of sol-gel method on quartz and glass substrates. Optical and structural properties of films were given byUV-Visible spectra and XRD pattern respectively. The results have shown that transmittance, porosity and band gap reduced by increasing the annealing temperature. Thickness and refractive index of films increased with increasing the annealing temperature. Furthermore, structure of films has anatase type at 400, 600 and 800 oC and transforminto rutile phase at annealing temperature of 1000 oC.
