| Abstract | ||
| Formation of Aluminum (Al) Nanoparticles in water by femtosecond laser ablation is studied numerically by considering the effect of femtosecond laser parameters, target and liquid properties. The absorption of laser energy by Aluminum is simulated using Single-Temperature Model (STM) and results obtained from this model are compared with experimental studies. Classical Nucleation Theory is used to calculate free-energy of critical clusters production and size distribution of nanoparticles (NPs) as function of laser energy and pulse duration in femtosecond range by considering concentration and delay time during the laser generated plume expansion in liquid. Finally, we deduce and point the optimum condition for the growth of Aluminum NPs of desired size and dispersion using STM. | ||
