Abstract
The dynamics of gas-phase nanoparticle formation by pulsed laser ablation into background gases were examined by photoluminescence and Rayleigh scattering techniques. The ablation of Si into heavier Ar resulted in a uniform, stationary plume of nanoparticles while Si ablation into lighter He resulted in a turbulent ring of particles which propagated forward at 10 m/s. The effects of gas flow on nanoparticle formation, photoluminescence, and collection were also studied.
