Abstract

The preparation of thermochromic vanadium dioxide (VO₂) films in an economical way is of interest to realizing the application of smart windows. Here, we reported a successful preparation of self-assembly VO₂ nanoplate films on TiO₂ -buffered glass by a facile hydrothermal process. The VO₂ films composed of triangle-shaped plates standing on substrates exhibit a self-generated porous structure, which favors the transmission of solar light. The porosity of films is easily controlled by changing the concentration of precursor solutions. Excellent thermochromic properties are observed with visible light transmittance as high as 70.3% and solar modulating efficiency up to 9.3% in a VO₂ film with porosity of ∼35.9%. This work demonstrates a promising technique to promote the commercial utilization of VO₂ in smart windows.
