AbstractVanadium dioxide (VO ) is a key material for thermochromic smart window applications because of its Mott phase transition properties. However, the applications of VO have been restricted because of its drawbacks in performance, including high phase transition temperature (T ), low luminous transmittance (T ), limited solar energy modulation ability (ΔT ) and unpleasant color. Various studies have been undertaken to resolve these problems but the improvement in any one aspect is always accompanied by a deterioration of the others. This paper reports that Zr doping can simultaneously decrease T , increase T , improve ΔT and modify the color of VO foils. The T value decreased from 68.6 °C to 64.3 °C at 9.8% Zr-doping; meanwhile, the composite foils prepared from Zr-doped VO nanoparticles exhibited excellent luminous transmittance (up to 60.4%) and solar energy modulation ability (up to 14.1%). The experimental optical band gap was 1.59 eV for the undoped VO , which increased to 1.89 eV at 9.8% doping. As a result, the color of the Zr-doped foils was modified to increase their luminous transmittance and lighten the yellowish color of the VO foil. The first-principles calculation was in good agreement with the experiment results. The W-Zr-codoped VO nanoparticles were prepared to further decrease the transition temperature (28.6 °C), while simultaneously maintaining the luminous transmittance (48.6%) and solar energy modulation ability (4.9%) of the derived foils. © the Partner Organisations 2014.
