Thermochromism of VO2 Nanoparticles: Calculated Optical Properties and Applications to Energy Efficient Windows

Abstract

ABSTRACTThermochromic materials have temperature-dependent optical properties. This paper discusses the limitations of thermochromic VO2 films for energy efficient fenestration and shows from calculations that nanocomposites containing VO2 can have superior properties and display high luminous transmittance and large temperature-dependent solar transmittance modulation. Even better results may be found for nanoparticles of VO2:Mg.
