The techniques of silver-sodium ion exchange and Ag+ion implantation in glass have been successfully applied for producing silver clusters in soda-lime glass optical waveguides. Optical absorption spectroscopy, time and spectrally resolved photoluminescence, Rutherford backscattering spectrometry, X-ray photoelectron spectroscopy and transmission electron microscopy measurements were made. Structural changes of the Ag+environment were observed in ion-exchanged samples prepared in liquids with different Ag+concentrations. Heat treatments in air and in H2atmospheres induced cluster formation in ion-exchanged samples through different reduction-migration mechanisms, whereas clusters formation in ion-implanted samples is related to the defect concentrations induced by the radiation damage.
