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.
