Lithium-doped tungsten oxide can be used to fabricate electrochromic device in the form of a thin film with better coloration and electrochromic properties than undoped tungsten oxide. According to the researchers, the electrochromic films can be prepared by electron beam evaporation on ITO glasses under the parameters of room temperature, with thicknesses of about 530 nm. Wherein, xLi2O-(1−x)WO3 powders were mixed with WO3 and Li2O and pressed into target pellets.

Tungsten oxide coating is well-known as a popular heat insulation coating because of the optical properties of tungsten oxide – high shielding performance to near infrared light and ultraviolet light and high transmittance to visible light. So, the production of tungsten oxide coating has been attracting much attention. It has been reported that tungsten oxide coating can be prepared via a sol-gel type process from tungstic chloride and tungstic acid precursors. Wherein, various combinations of ethanediol and block co-polymers are used as stabilizing additives to achieve microstructural control.

Tungsten oxide has good electro-optical properties to exhibit good electrochromic behavior so that it is used to manufacture electrochromic coating. Well, do you know how to gain the optical indices of tungsten oxide electrochromic coating?

Amorphous tungsten oxide may be applied to fabricate heat insulation film for applications of window glasses and glass curtain walls of buildings, and windshield windows of autos. Some experts have deposited the amorphous tungsten oxide film by pulsed laser deposition. And they investigated the correlation between morphology, composition, and the mechanical properties of metallic amorphous tungsten-oxygen and heat insulation film of amorphous tungsten oxide by the combined use of Brillouin spectroscopy and the substrate curvature method.
