Particle Dynamics in Laser Ablation Plume During Nanoparticle Synthesis (Invited

Particle dynamics in laser ablation plume in the background gas during nano-particlesynthesis are described, based on the results of the imaging diagnostics. Laser-inducedfluorescence (LIF), a newly developed re-decomposition LIF (Red-LIF) and Rayleigh scattering have been used to visualize the behaviors of atomic and molecular species, clusters andnano-particles, respectively. The influences of the kind of the background gas on the formation process of the nanoparticle and of an external electr
