摘要：

We described the influence of a type of gas and its pressure upon the size distribution of Si nanoparticles fabricated by laser ablation in an ambient gas and the plume dynamics during the synthesis. The plume dynamics was investigated by laser-induced fluorescence anti ultraviolet Rayleigh scattering. Based on the results, the importance of the gas flow within the ablation plume in the formation of the nanoparticles is understood.
