TiO2-doped MoO3 electrochromic thin films via sol-gel method

Abstract

MoO3 films allow high intercalation rate, but deintercalation is difficult to perform. It is the reason the MoO3 film has lower response time for use as electrochromic display materials. The effect of additive on the electrochromic property of MoO3 thin films produced by sol-gel method has been studied. The pure and TiO2-doped MoO3 thin films were characterized optically and electrochemically in LiClO4-propylene carbonate solutions. The experimental results showed that the additive of TiO2 had improved remarkably the cyclic stability and reversibility of the MoO3 film electrochromic electrode.
