Tungsten oxide is regarded as the most promising electrochromic material owing to its continuously tunable optical properties, low cost, and high coloration efficiency. Further improving its optical modulation, switching speed, and coloration efficiency is important to electrochromic smart windows and related devices. Here, we demonstrate an enhanced electrochromic film composed of a WO(3) nanosheet and ITO nanoparticles developed by an all-solution technology. The WO(3) nanosheet is fabricated by an acid-assisted hydrothermal process with high product efficiency. The introduction of an ITO in...
