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.
