DESCRIPTION:Speakers: Anna Kozakiewicz (Wits)\nMetal nanoparticles (MNP) w
 ere synthesized by room temperature ion implantation of high fluences (fro
 m 6x1016 to 5x1017 cm-2) of 150 keV Ag and 15 -22 MeV Au ions into Al2O3 a
 nd MgO single crystals.\nOptical absorption (OA) spectra show surface plas
 mon resonance (SPR) bands characteristic of the implanted metal ions. Upon
  annealing (300°-1200°C) the optical response of the metal nanostructure
 s changes\, related directly to their morphology\, shape and size. High re
 solution transmission electron micrographs indicate that the particles are
  often crystalline. The implanted ions profiles were obtained from 1.6 MeV
  He+ Rutherford Backscattering (RBS) for the silver implanted substrates a
 nd High Resolution Transmission Electron Microscopy (HRTEM)\, revealed bur
 ied layers of implanted ions.\n\nhttps://events.saip.org.za/event/7/contri
