Abstract

The aim of this study was to determine the optical properties of WO₃ and Zr doped tungsten oxide films deposited by the sol-gel process. The optical properties of WO₃ and Zr doped tungsten oxide films deposited by the sol-gel process depend on the number of coating layers. The refractive index and absorption coefficient of WO₃ thin films increases with an increasing number of deposited layers. Transmittance of Zr doped tungsten oxide thin films are greater than tungsten oxide thin film. A scanning electron microscope was used for the analysis of surface structure. Optical constants of tungsten oxide and zirconium tungsten oxides were determined by using spectrophotometric transmissivity in the UV-Visible region.
