The electrochromic behavior of tungsten(VI) oxide makes WO3 an attractive material for electronic devices.1 Partial reduction of colorless WO 3 generates an intense blue color assigned to inter-valence charge transfer in partially reduced WO3. The electrochemical reduction of tungsten(VI) to tungsten(V) is accompanied by uptake of cations

Tungsten oxide (WO 3), a typical photochromic material, has attracted considerable attention. So far, many advances have been achieved in different subfields of WO 3 photochromism, mainly focused on the enhancement of WO 3 photochromic properties, which depends not only on the chemical features but also on the microstructures, interface and hybrid components.
However, it bleaches thermally and in presence of oxidizing atmosphere. The formation of colour-centres is associated with increased electrical conductivity of the film.
