Dependence of optical properties of implanted silver nanoparticles in float glass on substrate temperature

The influence of temperature of the float glass substrate on Ag nanoparticle synthesis during GO keV Ag-implantation was studied with the doses from 2 to 4x10(16) ion/cm(2) at a current density of 10 mu A/cm(2) over the Surface-Glass Temperature (SGT) ranging from 60 degrees C to 180 degrees C. Detailed evaluations were made of the dose contribution on particle growth at the Bulk-Glass Temperatures (BGT) of 20 degrees C and 60 degrees C, The particle size distribution was assessed via optical reflectance, combined with Rutherford backscattering analysis. There is a major reduction in reflectance with increasing implant temperature of the glass surface. The samples prepared with the highest dose at 60 degrees C were characterised by more complex reflectance spectra, with overlapping peaks. compared to reflectance data for low temperature implants. Explanations for the observed optical dependencies and growth of metal nanoparticles are proposed. (C) 1999 Elsevier Science B.V. All rights reserved.
