Preparation of high transmittance TiO₂ thin films by sol-gel technique as antireflection coating

Abstract

In this present work sol-gel technique with spin coating method is used to deposit Titanium dioxide thin films on glass substrates as anti-reflection coating (ARC) films.Nano crystalline TiO 2 (anatase phase) is obtained after heating at 550°C for 2 h.The optical properties of TiO 2 films were studied by UV-Vis absorption/reflection spectroscopy, the average transmittance of monolayer coated on glass substrates was greater than 95% in the wavelength range of 300-1000 nm.
