Synthesis and characterisation of W-doped VO2 by Aerosol Assisted Chemical Vapour Deposition

W-doped vanadium dioxide thin films were deposited by Aerosol Assisted Chemical Vapour Deposition. Samples were characterised with several different techniques (i.e. X-ray Diffraction, Raman, Scanning Electron Microscopy-Energy Dispersive X-ray Analysis), to determine their composition and morphology. A study of their optical properties was also performed, to test the suitability of these materials as intelligent window coatings. Good changes in the transmittance and reflectance were observed above the transition temperature (decrease and increase respectively). A linear decrease in the transition temperature with increasing tungsten content was also seen, lowering it to room temperature. © 2007 Elsevier B.V. All rights reserved.
