Substoichiometric tungsten oxide films (WO 3−y , 0.49≥y≥0.15) were prepared by non-reactive thermal evaporation of WO 3 powder in vacuum. The thin film composition, structure and optical properties were investigated with the purpose to establish their dependence on the deposition conditions and to prove a possible correlation between electrochromic and gasochromic colouration. An analogy...
Tungsten oxide films with varied substoichiometry were deposited by reactive DC-sputtering from a W target at different oxygen partial pressures. The inherent maximum achievable electrochemical colouration and electrocolouration were found to be dependent on the oxygen content and consequently on the film substoichiometry. These results were related to those obtained in a previous study by colouration...
