Paper Abstract

Tungsten tri-oxide thin films were prepared by deposition from a solution of tungsten chloride, and, for comparison, by the acidification of a solution of sodium tungstate. The mechanism of the formation of HWO3 is explained in terms of oxidation of WC16 by O2. followed by chlorination of alcohol and formation of H2 which reduces WO3 to HWO3. The electrochromic behavior of these films was investigated by studying their current-voltage behavior, absorbance spectra, response time, and the diffusion coefficient of lithium ions in the film.
