The influence of different thickness on the physical properties of tio2 thin films prepared by chemical thermal evaporation

Abstract EN

TiO2 thin films with different thickness on some substrates of glass by using thermal evaporation method.

The result of optical properties illustrated that the best transmitted appeared at thickness (100 nm) and 900 nm wavelengths with a value equal to 78.2%.

The observed band gap value of the direct transitions energy 3.69 eV for 150 nm, 2.95 eV for 300 nm and 2.45 eV for 450 nm.
