Bismuth nanoclusters have been formed in optical grade silica glass (Corning 7940) by ion implantation which formed localized Bi:SiO2 composite in the near-surface region. Subsequent irradiation with 248 nm KrF excimer laser light modifies the distribution and chemical states of the implanted bismuth in the composite. Excimer laser irradiation causes not only photochemical reactions in the composite leaving a thin film of bismuth oxide on the surface, but also removal of the precipitated particles by both thermal and nonthermal desorption mechanisms from the surface.
