The Effect of Ag3PO4 on WO3 Electrochromic Film

WO3/Ag3PO4 electrochromic films were prepared by sol-gel and dip coating methods. The synthesized films were smooth having amorphous structure. The 0.8 wt% Ag3PO4-doped WO3 films displayed best electrochemical properties and optical modulation due to the effect of Ag3PO4 on reduction of band gap ene...

Description
Summary:WO3/Ag3PO4 electrochromic films were prepared by sol-gel and dip coating methods. The synthesized films were smooth having amorphous structure. The 0.8 wt% Ag3PO4-doped WO3 films displayed best electrochemical properties and optical modulation due to the effect of Ag3PO4 on reduction of band gap energy and enhancement of electrons and ions diffusions. X-ray photo-electron spectroscopy (XPS) was used to confirm the presence of Ag+ from Ag3PO4 in WO3/Ag3PO4 electrochromic films. They exhibited reversible electrochromic property with fast switching time when compared to that of pure WO3 film.
