Tungsten Trioxide (WO3) thin film is a kind of dingal material with large transmittance change, good reversibility, low relative price, long life, non-toxicity and environmental protection, and it is the earliest and most widely used electrochromic material. The application of this electrochromic material is hidden in our daily life. For example, it can be made into smart windows, which can save energy, dim light, control heat load and other dings. Therefore, in order to study the properties of Tungsten Trioxide…
