Vanadium dioxide (VO) coating plays an important role in energy saving and environmental protection due to its unique reversible phase transition. To solve the daylighting issue of VOcoating, a VO(M)-silicon dioxide (SiO) composite coating is fabricated from ammonium citrato-oxovanadate(IV) by a SiO-assisted coating method. The VO(M)-SiOcomposite coating possesses excellent thermochromic properties that have produced varying results, i.e. 49.2% of visible transmittance, 52.3% of transmittance reduction at 2000 nm wavelength, 12% of solar energy modulation (Δ) and a phase transition temperature of 56.0 °C. Our findings may pave the way to extending the large-scale application of smart windows based on thermochromic VO.
二氧化钒（VO）涂层由于其独特的可逆相变，在节能和环境保护方面发挥着重要作用。为了解决VO涂层的采光问题，采用SiO辅助涂层法，由柠檬酸氧钒（IV）铵制备了VO（M）-二氧化硅（SiO）复合涂层。VO（M）-SiO复合涂层具有优异的热致变色性能，产生了不同的结果，即49.2%的可见光透射率、在2000nm波长处52.3%的透射率降低、12%的太阳能调制（Δ）和56.0°C的相变温度。我们的研究结果可能为扩大基于热致变色VO的智能窗户的大规模应用铺平道路。
