Vanadium dioxide/titanium nitride (VO₂/TiN) smart coatings are prepared by hybridizing thermochromic VO₂ with plasmonic TiN nanoparticles. The VO₂/TiN coatings can control infrared (IR) radiation dynamically in accordance with the ambient temperature and illumination intensity. It blocks IR light under strong illumination at 28 °C but is IR transparent under weak irradiation conditions or at a low temperature of 20 °C. The VO₂/TiN coatings exhibit a good integral visible transmittance of up to 51% and excellent IR switching efficiency of 48% at 2000 nm. These unique advantages make VO₂/TiN promising as smart energy‐saving windows.

用于室温应用的VO2 / TiN等离子热变色智能涂料

二氧化钒/氮化钛（VO ₂ / TiN）智能涂料是通过将热致变色VO ₂与等离激元TiN纳米颗粒混合制备的。VO ₂ / TiN涂层可以根据环境温度和照明强度动态控制红外（IR）辐射。它在28°C的强光下会阻挡红外光，但在弱辐射条件下或在20°C的低温下是红外透明的。VO ₂ / TiN涂层在2000 nm处具有高达51％的良好整体可见光透射率和48％的出色IR转换效率。这些独特的优势使VO ₂ / TiN有望成为智能节能窗户。
