WO3 electrochromic thin film for energy-efficient window can be prepared by traditional preparation methods, such as hydrothermal method, sol-gel method, evaporation method, sputtering method, electrodeposition method, and pulsed laser deposition method. Also, the WO3 film can be synthesized by a new method combining a liquid laser ablation technique and an electrophoretic deposition method.

Compared with the traditional preparation method, the new method has the following advantages. The liquid phase laser ablation technology can be used to adjust the laser and solution parameters in the liquid environment to obtain a highly active and highly hybridized WO3 product. The operation is simple, the preparation process is fast, the reaction conditions are mild, and the control is easy. The prepared WO3 electrochromic thin film has high coloring/decoloring contrast and fast response. You know, the energy-efficient window is of great importance as global warming intensifies. And the environmentally friendly WO3 electrochromic thin film, as an important material for preparing such a window, is also receiving more and more attention.
