Gasochromic devices

The preparation and characterization of vanadium oxide (V2O5) modified tungsten oxide (WO3) films by pulse laser deposition were recently examined [61]. Tungsten oxide coatings are used in many electro-optical applications including catalysts, solar cell windows, electrochromic and gasochromic devices, optical memory and... 

It is also worthwhile to mention that gasochromic devices have been made by the sol-gel process (Georg, 2004) using WO3 layers prepared by the ion exchange or perox-opolytungstic acid method.
