Comparison Between Electrochromic and Photochromic Coloration Efficiency of Tungsten Oxide Thin Films

Research output: Contribution to journal › Article › peer-review

Abstract

We investigated the photochromic (PC) and electrochromic (EC) behavior of sputtered tungsten oxide (WO3-y) films with different oxygen deficiency y. It was found that both the PC and EC coloration efficiency increase with increasing oxygen deficiency in tungsten oxide. For PC efficiency, this behavior is consistent with the model of photochromism developed recently. A recently developed modelbased on the small polaron transition between W5+ and W4+ states has been used to explain the dependence of EC coloring efficiency on the oxygen deficiency in tungsten oxide fims This new mechanism also revelased a close relationship between PC and EC.
