Tungsten Oxide Applied for Smart Heat Insulation Film 20

The discoloration process of tungsten oxide for preparing smart heat insulation film is more complicated, and the mechanism is still controversial. Currently, the widely accepted and applied discoloration model is the dual injection model, namely the Fanghnan model. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html The Fanghnan model states that when ions are injected, the tungsten trioxide electrochromic film exhibits a blue color, and at this time, the ion injection is equivalent to the doping of the semiconductor. When the ions are…

WO3 Applied for Large Area Electrochromic Device 19

WO3 for preparing large area electrochromic device is in an amorphous state (a-WO3) at 300 °C and in a crystalline state (c-WO3) at 400 °C and 500 °C. Experts say that the amorphous tungsten trioxide film has higher coloring efficiency and shorter response time than the crystalline tungsten trioxide film. It means that a-WO3 film has better electrochromic performance than c-WO3 film. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Experts also introduced that, in general, tungsten oxide produced at lower temperatures is…
