  • Dipole-dipole plasmon interactions in gold-on-polystyrene composites 
    Peceros Katia; Xu Xiaoda; Bulcock Shaun; Cortie Michael (American Chemical Society, 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 ...
  • In Situ Precipitation of Gold Nanoparticles onto Glass for Potential Architectural Applications 
    Xu Xiaoda; Stevens Michael; Cortie Michael (American Chemical Society, 2004)
    The optical properties of in situ deposited gold nanoparticle coatings are investigated for potential application in architectural glass. It is found that the optical properties of the coating can be controlled by the ...
  • Precious metal core-shell spindles 
    Cortie Michael; Xu Xiaoda (Australia and New Zealand Third Sector Research, 2004)
    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 ...
  • Precious metal coreshell spindles 
    Xu Xiaoda; Cortie Michael (American Chemical Society, 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 ...
  • Shape Change and Color Gamut in Gold Nanorods, Dumbbells, and Dog Bones 
    Xu Xiaoda; Cortie Michael (Wiley-VCH Verlag GmbH, 2006)
    It is shown here that deviations from 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 ...
  • Shape change and color gamut in gold nanorods, dumbbells, and dog bones 
    Xu Xiaoda; Cortie Michael (Wiley-V C H Verlag Gmbh, 2006)
    It is shown here that deviations from 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 ...
  • Spectrally-selective gold nanorod coatings for window glass 
    Xu Xiaoda; Gibbons Thomas; Cortie Michael (World Gold Council, 2006)
    The unique optical properties of gold nanorods, which exhibit tuneable absorption as a function of their aspect ratio, suggest that they might have potential applications in coatings for solar control on windows. Here ...
  • The versatile colour gamut of coatings of plasmonic metal nanoparticles 
    Xu Xiaoda; Kealley Catherine; Maaroof Abbas; Cortie Michael (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 ...
