摘要: An investigation was conducted into the electrochromic properties of organotungsten oxide WOxCy films synthesized onto 60 Ω/□ flexible polyethylene terephthalate/indium tin substrates using low temperature, plasma-enhanced chemical vapor deposition (PECVD) at varying oxygen concentrations. The PECVD-synthesized were proven to offer remarkable performance. Cyclic voltammetry switching measurements revealed that only driving voltages from −1 1 V are needed provide reversible Li+ ion intercalation and de-intercalation in a 0.1 M LiClO4–PC electrolyte. Light modulation with transmittance variation up 72.9% coloration efficiency 62.5 cm2/C wavelength 650 nm obtained.
