Abstract:

Noble metallic nanoparticles-glass composites have attracted much interest because of their technical potential as nonlinear media. In present work, the influences of ion-exchange and thermal treatment on the photoluminescence of noble metal doped silicate glasses were discussed based on photoluminescence (PL) spectroscopy and ligand field theory. The results indicate that metallic ion concentration in silicate glass increases with extending ion-exchanged period. There exist isolated Ag+ ions and Ag2+ clusters in Ag-doped silicate glass. Concentration of the isolated Ag+ ions decreases quickly and Ag32+ clusters appear after annealing the Ag-doped silicate glass in H2. While there exist only isolated Cu+ and Cu2+ ions in the Cu-doped silicate glass, no photoluminescence of Cu+ clusters are found in the glass. The existence of Cu2+ ions makes the luminescence of Cu+ quenching. It is very difficult to introduce Cu+ ions into the annealed Ag-doped glass in H2 via Cu+ for Na+ ion-exchange.

Key words: ion-exchange, thermal treatment, nobel metallic ions and clusters, photoluminescence, ligand field theory
