Notes:
WO3 and Ti-doped WO3 electrochromic films were prepared by mid-frequency dual-targetmagnetron sputtering method. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS),transmission electron microscope (TEM) and spectrophotometer were used to characterize thestructure, morphology, composition and transmittance properties of the films, respectively. Theresults show that this method is available to deposit WO3 and Ti-doped WO3 electrochromic films.The as-deposited films prepared at room temperature are amorphous and display good transmittance.The difference value of transmittance between the bleached and coloration states of WO3 film isabove 60% at 633nm. Ti-doped WO3 films have smoother surface and smaller grains than undopedones. Moreover, the crystalline temperature increases after doping titanium, because the titaniumatoms influence the lattice distortion of the WO3 films. So it is more convenient for Li+ ions to injectinto films and can enhance the response speed and stability of Ti-doped WO3 electrochromic films
