Abstract

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 .

Highlights

In the recent years TiO2 films are widely studied because of their perfect photocatalytic properties

Summary

INTRODUCTION

In the recent years TiO2 films are widely studied because of their perfect photocatalytic properties. TiO2 thin films find a broad range of applications in various fields like photocatalysis , antireflective ,gas sensing , antibacterial, protective coatings and optical coatings, dielectric films for a new generation field effect transistors, etc.[1]. Its not sensitivity to the visible light, because of its band gap , which have value (3.2) eV [2].Some techniques including spray pyrolysis, sol–gel coating, chemical vapor deposition , rf magnetron sputtering have been advanced for TiO2 thin films manufactures. TiO2 films prepared from these mechanism exhibit a broad variety of optical properties and structures [3].From across existing techniques, sol-gel. The processing of sol gel is essentially efficient to producing transparent, thin ,multi-component oxide layers of various compositions on many substrates, counting glass[4]
