| Popis: |
UV irradiation is used to precharge sputtered tungsten trioxide (WO3) on polyethylene terephthalate enhancing the photochromic response with organic solvents. A comparison between the optical and electrochemical properties of photochemically and electrochemically charged WO3 results in a correlation of the transmittance to the respective charge density. This allows for a precise control of the charge density in the precharging process monitored by UV-Vis spectroscopy. A proof-of-concept flexible electrochromic device combining precharged WO3 (charge density: 20 mC cm-2) and Prussian blue (15 mC cm-2) exhibits a superior change in the visible light transmittance (τv) from 8% (dark) to 79% (bleached) and a coloration efficiency of 139 cm2 C-1 at 716 nm. |
