Abstract

The realization of colorful effects based on inorganic electrochromic materials has always been a focus of research in the field of electrochromism. In recent years, colorful electrochromic devices based on Fabry-Perot cavity have received a lot of attention. This article uses three metals (chromium, copper and tungsten) and tungsten trioxide to form Fabry-Perot cavity, and tests these electrochromic devices (ECDs). The results show that Fabry-Perot cavity electrochromic devices based on these three metals can achieve colorful effects, among which ECD using tungsten as reflector has the best performance, with an optical modulation range of reflectivity of 27.67 %. The CIE color coordinates change from (0.235, 0.300) to (0.241, 0.181), and the response times for coloring and bleaching are 4.0 s and 6.1 s, respectively. ECD using chromium as reflector is similar to ECD using tungsten as reflector in reflectance spectra, ECD using copper as reflector has a fast response speed but performs poorly in terms of cycle life. By comparing the differences in device performance caused by three types of metal reflective layers, we believe that metals with strong reflection, good conductivity, and chemical stability can perform better in such electrochromic device.

期刊介绍： This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
