TLDR
In this paper, the electrochromic response of tungsten oxide films deposited in a pure oxygen atmosphere was found to show the best value at an O/W ratio of 2.5.Abstract:
The electrochromic response of tungsten oxide films deposited in a pure oxygen atmosphere was found to show the best value at an O/W ratio of 2.5. When argon was introduced into the atmosphere, the response became faster, as the total pressure increased. However, the best response values, for films deposited in an atmosphere containing oxygen, were usually attained at a fixed partial pressure of oxygen. The factors determining the electrochromic response in a cell utilizing atmospheric evaporated tungsten oxide films (AETOF) were analyzed, and the dependence of the film formation conditions on these factors was investigated.read more

Electrochromic mechanism in a-WO3−y thin films
TL;DR: In this paper, the electrochromic mechanism in amorphous tungsten oxide films was studied using Raman scattering measurements, and the authors concluded that the as-deposited films contain mainly the W4+ and W6+ states and the W5+ states are generated as a result of reduction of the W6+) states when lithium or hydrogen ions and electrons are inserted.
