Determination Of Optical Properties of Nanostructured Ti02 Thin Films

Abstract

This work presents some results on deposition and investigation of optical properties of Ti02 thfn films. Thin films of Ti02 were deposited onto optical glass substrates by doctor blade technique and the crystallization ofTi02 coating was then achieved through thermal annealing at a temperature of 400°C in a programmable furnace. The optical properties were by DUV spectrophotometer in the spectral range of 300-3000 nm. The optical properties were systematically studied by using the optical transmittance and reflectance data. The absorptance and energy band gap were evaluated. The energy band gap of Ti02 is found to be 3.3eV for the indirect band gap and 3.2eV for the direct band gap.
