High-Performance Thermochromic Multilayer Coatings of W-Doped VO <sub>2</sub> Nanoparticles Dispersed in an SiO <sub>2</sub> Matrix Prepared on Glass at a Low Temperature
We report a high-performance thermochromic VO<sub>2</sub>-based coating prepared on standard glass at a low substrate temperature of 350 °C without opening the vacuum chamber to the atmosphere. It is formed by four layers of W-doped VO<sub>2</sub> nanoparticles dispersed in the SiO<sub>2</sub> matrix. The coating exhibits a transition temperature of 33 °C with an integral luminous transmittance of 65.4% (low-temperature state) and 60.1% (high-temperature state), and a modulation of the solar energy transmittance of 15.3%. Such a combination of properties, together with the low temperature during preparation, fulfills the requirements for large-scale implementation on building glass and has not been reported yet.
