主　　题：Electrochromic High brightness Tungsten trioxide Copper 

摘      要：Fabry-Perot(F-P)nanocavity-type electrochromic devices with multicolor tunability have attracted significant interest in the past two years for their potential uses in a wide variety of applications,such as electronic display,military camouflage,and dynamic ***,challenges such as insufficient brightness,lengthy switching times,and poor cycling stability have yet to be ***,we demonstrate electrochromic electrodes based on ITO/Cu as both the current collector and the reflective layer,with WO_(3 )as the electrochromic material,forming a unique three-layered *** constituted WO_(3 )/ITO/Cu films present a high brightness value of about 84%before coloration,and a decent brightness value of 48%after coloration at−0.8​***,a fast switching time between different coloration states(tc​=​2.2​s;tb​=​1​s)is recorded,attributed to the extremely low sheet resistivity of the ITO/Cu current *** films also reveal excellent electrochemical cycling stability across 2000 cycles.
