Abstract

Nanoparticles of silicon oxide alloys (i.e., oxides of SiMo, SiPt, and SiAl) are produced by laser vaporization of a silicon target and a target of a metal (i.e., Mo, Pt, or Al), in an oxygen containing atmosphere in a diffusion cloud chamber, where the target metal vapors aggregate into novel three-dimensional porous web structures. The structures have a homogeneous composition with a uniform ratio of silicon to the metal.
