Abstract
Studies of electrochromism in evaporated and chemically prepared tungsten-oxide films have shown that electrocoloration takes place only in films containing H2O. A model is proposed in which the electrocoloration process is attributed to the formation of a ‘tungsten-blue’ phase following cathodic reduction by active hydrogen.Keywords
