Porous vanadium dioxide thin film-based Fabry-Perot cavity system for radiative cooling regulating thermochromic windows: experimental and simulation studies.

Radiative cooling in smart windows using VO - a dynamic thermal management material, is of potential interest for enhancing energy savings in buildings due to its both solar and emittance tuneability in response to changing temperatures. However, studies related to the effects of VO thin film microstructure in a multilayer system on emissivity regulation are currently lacking. The present study addresses the thermochromic and emissivity performance of VO/ZnSe/ITO/Glass Fabry-Perot (F-P) cavity thin film system, by manipulating the porosity in VO thin film.

Femtosecond Laser-Induced Vanadium Oxide Metamaterial Nanostructures and the Study of Optical Response by Experiments and Numerical Simulations.

Surface patterning is a popular approach to produce photonic metasurfaces that are tunable when electro-optic, thermo-optic, or magneto-optic materials are used. Vanadium oxides (VO) are well-known phase change materials with many applications, especially when used as tunable metamaterial photonic structures. Particularly, VO is a well-known thermochromic material for its near-room-temperature phase transition from the insulating to the metallic state.
