Recent Advances in Fabrication of Flexible, Thermochromic Vanadium Dioxide Films for Smart Windows.

Monoclinic-phase VO (VO(M)) has been extensively studied for use in energy-saving smart windows owing to its reversible insulator-metal transition property. At the critical temperature (T = 68 °C), the insulating VO(M) (space group P21/c) is transformed into metallic rutile VO (VO(R) space group P42/mnm). VO(M) exhibits high transmittance in the near-infrared (NIR) wavelength; however, the NIR transmittance decreases significantly after phase transition into VO(R) at a higher T, which obstructs the infrared radiation in the solar spectrum and aids in managing the indoor temperature without requiring an external power supply.
