Abstract

We have investigated the formation process of nanoparticles in the laser ablation plume by different laser imaging spectroscopy techniques, such as Two-Dimensional laser induced fluorescence (2D-LIF), UV Rayleigh scattering (UV- RS), and Re-Decomposition LIF (ReD-LIF). Clusters, which are hardly observed by the UV-RS method due to their small size, are observed by the ReD-LIF method. The dynamics and formation processes of the nanoparticles, which are synthesized in the Si or ZnO ablation plume, is presented.
