Electrochromic properties of nanostructured tungsten trioxide (hydrate) films and their applications in a complementary electrochromic device

Orthorhombic hydrated tungsten trioxide (3WO3·H2O) films consisted of nanosticks and nanoparticles were prepared on fluorine doped tin oxide (FTO)-coated substrate by a facile and template-free hydrothermal method using ammonium acetate (CH3COONH4) as the capping agent. Irregular nanobrick films wer...

description Orthorhombic hydrated tungsten trioxide (3WO3·H2O) films consisted of nanosticks and nanoparticles were prepared on fluorine doped tin oxide (FTO)-coated substrate by a facile and template-free hydrothermal method using ammonium acetate (CH3COONH4) as the capping agent. Irregular nanobrick films were obtained without capping agent. Due to the highly rough surface, the nanostick/nanoparticle film depicts faster ion intercalation/deintercalation kinetics and a greater coloration efficiency (45.5 cm2/C) than the nanobrick film. A complementary electrochromic device based on the nanostick/nanoparticle 3WO3·H2O film and Prussian blue (PB) was assembled. As a result, the complementary device shows a higher optical modulation (54% at 754 nm), a larger coloration efficiency (151.9 cm2/C) and faster switching responses with a bleaching time of 5.7 s and a coloring time of 1.3 s than a single 3WO3·H2O layer device, making it attractive for a practical application.
