Observation of Nanoparticle Formation Process by Two-Dimensional laser induced fluoresence, UV Rayleigh scattering and Re-Decomposition Laser Induced Fluorescence methods

摘要

We have investigawted 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.
