研究目的
To prepare monolayer hollow spherical tungsten oxide (WO3) films with enhanced near infrared electrochromic performances using magnetron sputtering combined with the colloidal crystal template method.
研究成果
The hollow spherical WO3 films exhibit enhanced electrochromic performance with high transmittance modulation, fast switching response time, and high coloring efficiency in the near-infrared region, making them promising for smart windows.
研究不足
The study does not address the long-term stability and durability of the hollow spherical WO3 films under operational conditions.
