Tungsten Trioxide Nanoparticles Applied for Electrochromic Smart Glass

Tungsten trioxide nanoparticles for producing electrochromic smart glass are a type of inorganic electrochromic material with excellent chemical stability and long service life. According to the experts, WO3 is the focus of research. And the obtained tungsten oxide smart glass is a building energy-saving glass that can dynamically control the radiant heat of light in the sun in accordance with the actual needs of people according to the changes in season and temperature.

As the first electrochromic material to be discovered, tungsten trioxide has the advantages of superior performance and low price, so it has become the most important (inorganic) electrochromic material. But why not choose organic electrochromic materials to produce electrochromic smart glass? Organic electrochromic materials have many advantages, such as low cost and rich color. However, this also cannot overcome the shortcomings such as weak chemical stability and poor radiation resistance, so its development in applications such as building smart windows is limited.
