Impedance Spectroscopy of Electrochromic Hydrous Tungsten Oxide Films

Spectroscopy Study of Amorphous Tungsten Oxide Films used in Electrochromic Multilayered Structures

Amorphous Tungsten Oxide (alpha-WO3) film is one of the most studied electrochromic (EC) materials. It can be used as EC layer in EC devices. Electrochromism can be described as reversible change optical properties, by an applied external voltage. Here alpha-WO3 thin films were deposited onto glass and ITO substrates by reactive DC magnetron sputtering for EC application. Growth temperature, ox...

Designing and Fabrication of Electrochromic Windows Using Tungsten Oxide Films Prepared Through Sol-gel Coating on a Glass

In this study, a sol-gel peroxotungstic acid sol was employed to deposit tungsten oxide (WO3) films by the spin-coating technique. In view of smart window applications, electrochromic windows were then designed and fabricated using a thin tungsten oxide film. For this purpose, Glass/ FTO/ WO3/ electrolyte/ FTO/Glass could be of use due to its special structure that consists of an electrochromic...

Infrared switching electrochromic devices based on tungsten oxide

Infrared switching electrochromic devices based on tungsten oxide" (2000). Faculty Publications from the Department of Electrical and Computer Engineering. 4. Different types of electrochromic devices for thermal emittance modulation were developed in the spectral region from mid-to far-infrared ͑2–40 ␮m͒. In all devices polycrystalline and amorphous tungsten oxide have been used as electrochromi...
