Solar Cells,Electrochromism in Nickel Oxide and Tungsten Oxide Thin Films. The colours of the tungsten oxides are a result of the fact that the absorption and emission of photons (light) are dependent on wavelength. If the material has a low reflectivity at the short wavelength end of the spectrum (460 – 480 nm) it appears yellow to orange, because only the green and yellow part of the light is reflected.

APPLICATIONS OF TUNGSTEN OXIDE. Tungsten oxide is used for many purposes in everyday life. It is frequently used in industry to manufacture tungstates for x-ray screen phosphors, for fireproofing fabrics and in gas sensors. Due to its rich yellow color WO3 is also used as a pigment in ceramics and paints. The colour centre, thus formed, shows a slight bleaching with light. However, it bleaches thermally and in presence of oxidizing atmosphere. The formation of colour-centres is associated with increased electrical conductivity of the film.

Yttrium-Oxide Tungsten Electrodes Electrodes with yttrium oxide added (WY) provide similar benefits to cerium oxide. 2% yttrium-oxide tungsten electrodes are color coded blue (ISO only). Yttrium is sometimes used in proprietary “rare earth” blends. Zirconium-Oxide Tungsten Electrodes Colour coding with pure tungsten is: Green = W – made of pure tungsten without any oxide component. WZr. The addition of zirconium oxide means that the risk of contaminating the fusion is very low.

Exact time and temperature control determine, to a large extent, the physical characteristics of yellow tungsten oxide.

No colouration is observed in fully oxidized samples of WO 3. 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 creating tungsten alloys that provide the same level of emission as pure tungsten at much lower temperatures, improving starting performance of the electrode, arc stability, and tip life. Each oxide has a different physical characteristic affecting tungsten performance. Electrodes are color coded, indicating the type of oxide used in the mix.
