Title: In Situ EXAFS and TEM Investigations of Ag Nanoparticles in Glass

Abstract

Ag particle-glass composites produced by ion exchange processes of soda-lime glasses were investigated by EXAFS spectroscopy at the Ag K-edge. The spectra measured at 10 K were used to characterize the structure of nanoparticles as a result of ion exchange. The evolution of Ag K-edge EXAFS oscillations measured by in situ heating at 823 K as a function of time clearly shows an increase of Ag-Ag distance and coordination number caused by annealing. Together with transmission electron microscopy characterization a preferred growth of Ag particles with respect to nucleation has been found that leads to increased particle sizes in deeper glass regions.
