| Research Abstract |
Well-ordered arrangements of Ag nanoparticles have been found for Ag-implanted SiO2 at depths corresponding to the projected range and end of range of Ag ions. X-ray photoelectron spectroscopy and x-ray diffraction confirm the stability of these Ag nanoparticles against oxidation and sulfidation when stored in ambient air for 19?21 months. For Ag nanoparticles deposited on SiO2, we utilized low-energy Ar ion irradiation and Ar plasma exposure to recover their plasmonic properties.
