Study the Effect of Thickness on Optical Properties of Titanium Dioxide (TiO2) That Preparation of Via the Sol-Gel Process

This research, study the effect of the thickness on titanium dioxide (TiO2) , that prepared by the Sol-Gel Process method on the optical properties of (TiO2) thin film with different thickness (54, 64 and 89 nm), the thickness effect on optical properties (energy gap , absorbance spectrum, transmittance spectrum, reflectance, refractive index, extinction coefficient, absorption coefficient, real and imaginary dielectric constant) ,this study shows that thickness have an effect on all these parameters .
