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.
