  • Abstract We successfully sol-gel synthesize electrochromic tantalum pentoxide (Ta2O5) coatings on indium tin oxide glass (ITO) at room temperatures. Compare to other tantala-based materials reported in the literature, our device is all-solid-state, with higher extinction, low-cost and a longer life-time. Ta2O5 is transparent over a wide range of wavelength. The coloration and bleaching states can be reversibly obtained for more than 60 cycles with an applied voltage as low as 3V. The achieved extinction is estimated to be over 20%. The coloring/bleaching response time is found in several seconds.
