Abstract

Vanadium dioxide is an intriguing candidate for use in intelligent devices such as sensors, magnetic refrigeration and particularly as solar modulating smart window materials. A facile sol-gel route is developed to produce pure VO2 with different nanostructures in a CO2 atmosphere. It was found that the nanoporous structures demonstrated a 16% increase in the luminous transmittance (Tlum) (from 20% to 36%) compared with the vacuum results, while large supercooling effects of up to 30°C have been observed in zero-dimensional structures.
