Thin films of tungsten oxide were prepared by D. C. sputtering of WO

ceramic target in Ar gas
the process is presented. SCE and XPS were employed to inverstigate the microstructure of the films and identify its chemical composition. The electrical and optical properties of the films were determined by cyclic voltammetry
spectral transmittance
current-time relationship and response time measurements. Our results indicate that the a-WO

thin films have good electrochromic characteristics.
