Color-changing Performance of Electrochromic Devices Based on WO_(3)/Pt-NiO Electrodes

将水热法和电沉积相结合制备WO_(3)/Pt复合薄膜并表征其组成、微结构和性能,将其作为阴极制做了WO_(3)/Pt-NiO电致变色器件并测试其性能。结果表明,WO_(3)/Pt-NiO电致变色器件具有较为迅速的时间响应(着色/褪色的为29.62/18.84 s)和适当的光调制范围(630 nm处为47%)。这种WO_(3)/Pt-NiO电致变色器件,具有大光调制、高着色效率和高开关速度等性能。

The application of electrochromic devices(ECDs)in smart windows provides new solutions for energy conservation and environmental protection.WO_(3)/Pt composite films for electrochromic cathodes were prepared through a combination of hydrothermal and electrodeposition methods.WO_(3)/Pt composite films of different deposition times were characterized and their electrochromic properties were examined.Next,NiO thin films were prepared by electrodeposition as electrochromic anodes.WO_(3)/Pt-NiO electrochromic devices were constructed with WO_(3)/Pt composite films and NiO films as color changing cathodes and anodes,respectively.The WO_(3)/Pt-NiO electrochromic device has a relatively fast response time(coloring/fading rate of 18.84/29.62 s)and a good optical modulation range(47%at 630 nm).Its designed ECD has the characteristics of large optical modulation,high coloring efficiency,and fast switching speed.These characteristics make WO_(3)/Pt-NiO electrochromic devices a very promising candidate for smart windows in lighting control and energy-saving applications,and their use as color-changing smart windows has broad application prospects in fields such as architecture,aircraft,and automobiles.
