Abstract
A web-like nanoparticle silica is produced by laser vaporization of silicon metal in a helium/oxygen atmosphere in a diffusion cloud chamber where it aggregates into novel web-like microstructures. The aggregates are porous and have a surface area greater than 300 m.sup.2 /g. Bright blue photoluminescence from the web-like nanoparticle silica is observed upon irradiation with ultraviolet light.
