- The WO3 film coated FTO glass exhibited the largest electrochemical contrast of 50% at 800 nm with Tmin = 7% and T max = 57%.
- XRD data revealed that the WO3 thin films formed monoclinic structures.
- The WO3 films changed from slight yellow to dark blue
- The deposition process using NPDS would be suitable for the mass production of inorganic electrochromic films.
