Ti-doped yellow tungsten oxide thin film has the same electrochromic properties as the tungsten trioxide thin film. Experts say that at present, the research on the electrochromic properties of Ti-doped tungsten trioxide film is mostly concentrated in chemical preparation methods, such as sol-gel method and hydrothermal method. And there are few reports on the preparation of Ti-doped WO3 thin film by reactive magnetron sputtering method.

They also introduced that, compared to chemical methods, the use of magnetron sputtering method to prepare Ti-doped yellow tungsten oxide film can improve the electrochromic properties of WO3 thin film while obtaining uniform thickness films on large-area substrates. And it can also realize large-scale production. However, in fact, the current research on the mechanism of affecting the performance of WO3 after Ti doping is not sufficient, and further research is needed to gain a deeper understanding, and therefore, to better know the electrochromic properties of Ti-doped WO3 film.
