Abstract
Tungsten (W)-doped vanadium dioxide (VO 2) particles were successfully synthesized by hydrolysis of vanadyl sulfate mingled with a small amount of sodium tungstate dihydrate and subsequent calcination. XPS analyses demonstrated that the vanadium oxide was composed of stoichiometric VO 2, and the doped W content in VO 2 particles could be easily controlled by the concentration of W precursor. XRD patterns indicated that all the W-doped VO 2 particles were monoclinic crystals, and the W dopant almost had no influence on the crystal structure of VO 2 particles. DSC analyses displayed that the critical phase transition temperature of VO 2 particles could be reduced to room temperature or even lower by increasing the doped W fraction. UV–vis–NIR spectra showed that the W-doped VO 2 particles embedded acrylic coating had very good thermochromic performance.
