WO3 thin film in the form of nanowires can be prepared into a gas sensor for efficient NO2 sensing. You know, NO2, mostly produced from exhaust fumes of cars and factories, has been labelled by the World Health Organization as one of the most hazardous air pollutants. Although metal oxide-based thin films have been employed to detect NO2 earlier, significant challenges remain to be addressed particularly at low detection limits. This is presumably undermined by the low surface area and…

Tungsten oxide is an electrochromic material that has been widely used as an electrochromic layer for assembling a new smart glass. The researchers have selected nano composite materials of tungsten oxide and niobium oxide to create such a smart glass. The substrate of the smart glass is amorphous niobium oxide, in which a tungsten oxide nanocrystal mesh-like structure is embedded. Although the two materials are electrochromic materials, their absorption spectra are different when they change color. Tungsten oxide nanocrystals absorb…
