LASER IRRADIATION INDUCED NARROW SIZE DISTRIBUTION AND CORE SHELL CLUSTERISATION OF Cu AND Ag NaNO CLUSTERS

Dielectrics with nano size metal inclusions are engineered composite materials, receiving substantial attention in the last decade due to their high third order dielectric susceptibility. Such nanocomposite materials are prepared either by direct implantation of metal into the dielectric matrix or by any of the multi step methodologies like binary ion exchange technique followed by suitable treatments like low mass ion irradiation, thermal or laser annealing. Post ion exchange treatments result in metal clusterisation and a predestined size distribution which is desired of any metal nanocomposite glasses. Present endeavor is aimed at the effect of laser ablation on the Cu, Ag and CuAg ion exchanged soda lime glass and by UV-VIS optical absorption measurements.
