Tungsten Oxide Thin Film

tungsten oxide electrochromic film

Tungsten oxide thin film is covering tungsten oxide thin film onto substrate of glass through deposition or other methods, has a variety of properties such as electrochromic, gas electrochromic, photochromic, thermochromic, and also excellent electrochemical property, thus to be widely used in smart color window, gas sensor, PH meter and so on.

Tungsten oxide thin film has optical, electrical, magnetic, chemical, mechanical, thermal property and can be applied in many fields, for example electrical, optical, hard, corrosion film ect..

Tungsten oxide thin film has studied extensively in aspects of gas sensor, electrochromic material, photoelectrode, ceramic target ect..

Tungsten oxide thin film has tremendous potential in gas-sensing property, tungsten oxide doped with different elements can be used as NH3, NO2, H2S, O3, O2and other gas-sensitive material under different conditions, and known as the most promising gas-sensitive material.

Research showed a method for preparing nano tungsten trioxide film, which takes ammonium paratungstate (APT) as raw material, through film growth process under high temperature, to prepare high-performance thin film for preventing particle agglomeration and shedding, to used in solar photoelectrochemical cell.
