  • Peceros, Katia; Xu, Xiaoda; Bulcock, Shaun; Cortie, Michael (Amer Chemical Soc, 2005)
    Red-shifting of the optical absorption spectra of aggregates of gold nanoparticles by dipole-dipole interactions is of considerable interest, both for theoretical reasons and because the phenomenon can be potentially ...
  • Xu, Xiaoda; Stevens, Michael; Cortie, Michael (American Chemical Society, 2004)
    The optical properties of in situ depositied gold nanoparticle coatings are investigated for potential application in architectural glass. It is found that the optical properties of the coating canbe controlled by the pH ...
  • Xu, Xiaoda; Cortie, Michael (Amer Chemical Soc, 2007)
    A simplified method to produce spindle-shaped particles with a hematite core and a silica shell is described. The silica shell can, in turn, serve as the substrate for an outer coating of Ag or Au nanoparticles. The resulting ...
  • Xu, Xiaoda; Cortie, Michael (Wiley-V C H Verlag Gmbh, 2006)
    It is shown here that deviations from a prolate ellipsoidal shape have a significant effect on the optical properties of gold nanorods. Transitions from rods to 'dumbbell'- or 'phi'-shaped particles lead to a shift in the ...
  • Xu, Xiaoda; Gibbons, Thomas; Cortie, Michael (World Gold Council, 2006)
    The unique optical properties of gold nanorods, which exhibit tuneable absorption asa function of their aspect ratio, suggest that they might have potential applications in coatings for solar control on windows. Here we ...
  • Kealley, Catherine; Cortie, Michael; Maaroof, Abbas; Xu, Xiaoda (Royal Soc Chemistry, 2009)
    We have investigated the colour gamut of coatings produced by the growth of plasmonically-active coatings of cap-shaped Au or Ag nanoparticles on a transparent substrate. The control of colour and spectral selectivity that ...
