At the edge between physics and chemistry, Pulsed Laser Ablation in Liquids (PLAL, sometimes called LASIS for Laser ablation synthesis in solution) is a versatile technological approach to producing nanoparticle colloids with ligand-free surfaces. Nowadays, this popular technique is increasingly employed in the areas of cell and molecular biology. The technique can be operated continuously and nanoparticle production rates of several grams per hour are obtained. Therefore, PLAL has aroused a lot of commercial interests recently. The team addresses two different topics: (i) the development of new materials and (ii) the understanding of the synthesis process. The team successfully synthesizes various doped insulators, metals, metallic sulfides for their optical properties or their catalytic properties. Despite this widespread use, the underlying mechanisms of PLAL are not fully understood yet. The PLAL involves high complexity and multiple time-scale transient physics and chemistry. When a pulsed-laser is focused into a solid target immersed in liquids, the material is evaporated and turns into a plasma. Nucleation and growth occur in the liquid confined bubble and nanoparticles are obtained. We aim to draw a complete picture of the processes. For that purpose, we developed in-situ diagnoses (plasma spectroscopy, imaging) coupled with numerical development in physical chemistry and hydrodynamics. This pluridisciplinary approach is innovative in the PLAL community.
