Ning W, Huang YZ, Magdassi S, Mandler D, Hai L, Yi L. Formation of VO2 zero-dimensional/nanoporous layers with large supercooling effects and enhanced thermochromic properties. [Internet]. 2013;3 (19) :7124 - 7128.
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 (T-lum) (from 20% to 36%) compared with the vacuum results, while large supercooling effects of up to 30 degrees C have been observed in zero-dimensional structures.
