Laser ablation in liquid (LAL) is one of the important technologies for preparing nanomaterials. In this article, Al nanoparticles (NPs) are fabricated by laser ablation in three different organic solvents. The thermodynamic properties within the bubble are studied using ultrafast camera and an analytical model based on Rayleigh–Plesset equation. Combined with the NPs characterization, the correlation between the bubble dynamics and the formation of NPs is discussed. The results show that complex physical and chemical reactions inside the bubble affect the bubble dynamics. At the same time, the bubble dynamics in turn affect the morphology and properties of the nanoproducts.
