Abstract

Enhanced surface segregation of Ag atoms has been experimentally observed during low dose-rate (∼0.6 A/cm2) implantation of 1 MeV silver ions (Ag+) into a soda-glass matrix at room temperature. Formation of various sizes of silver nanoclusters has further led to interesting optical properties, particularly at higher implantation doses. Drastic reduction in optical density and increase of resonance width has been explained as a result of segregated large clusters of silver atoms on the glass surface.
