Hexagonal WO₃ Electrochromic Film

Self-seeded one-step growth

In-situ grown on FTO via a one-step hydrothermal method using xylitol as self-seeding agent and cesium sulfate as capping agent, the film adheres strongly to the substrate and exhibits large optical modulation, combining electrochromic and pseudocapacitive properties.
