Yellow tungsten oxide nanopowder may be used to produce an electrochromic glass, that is, a smart glass with excellent optical adjustment properties. In other words, such smart glass is mainly used to achieve the effects of thermal insulation and heat preservation with high transparency so that it is more and more widely applied in the heat insulating field of construction and automotive glass. for such electrochromic material, experts say that the following reversible reactions occur when the WO3 film is…
