Reversible Zn(2+) Insertion in Tungsten Ion-Activated Titanium Dioxide Nanocrystals for Electrochromic Windows

Zinc-anode-based electrochromic devices (ZECDs) are emerging as the next-generation energy-efficient transparent electronics. We report anatase W-doped TiO(2) nanocrystals (NCs) as a Zn(2+) active electrochromic material. It demonstrates that the W doping in TiO(2) highly reduces the Zn(2+) intercal...

description Zinc-anode-based electrochromic devices (ZECDs) are emerging as the next-generation energy-efficient transparent electronics. We report anatase W-doped TiO(2) nanocrystals (NCs) as a Zn(2+) active electrochromic material. It demonstrates that the W doping in TiO(2) highly reduces the Zn(2+) intercalation energy, thus triggering the electrochromism. The prototype ZECDs based on W-doped TiO(2) NCs deliver a high optical modulation (66% at 550 nm), fast spectral response times (9/2.7 s at 550 nm for coloration/bleaching), and good electrochemical stability (8.2% optical modulation loss after 1000 cycles).
