Abstract
We report a high-performance thermochromic VO(2)-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(2) nanoparticles dispersed in the SiO(2) 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.
