摘要：A novel process was developed for preparing thermochromic VO2 film on commercial float glass by a low temperature V2O5 sol-gel method combined with a facile thermal reduction technique. The structure and optical properties of the films were determined by X-ray diffraction (XRD), Scanning Probe Microscopy (SPM), ultraviolet-visible (UV-Vis) spectroscopy and infrared (IR) spectroscopy. The as-prepared coating glass has larger transmittances at 343K than 293K from 717nm to 900nm, smaller transmittances at 343K than 293K from 2500nm to 4450nm. Through the thermochromic VO2 film the maximum transmittance difference between 343K and 293K is up to 50% in infrared wavelength.
