This study delves into the optimization of the nanosecond laser ablation on silicon wafer surface with pulsed laser ablation in liquid (PLAL) method for the synthesis of silicon nanoparticles. Through systematic experimentation, the researchers explored the influence of laser energy, environmental and solvent medium (air, water, ethanol and glycerin), and focusing techniques on the ablation efficiency of silicon wafers. The findings demonstrate a correlation between laser pulse energy and the size of the ablation zone, underscoring the crucial role of laser parameters and the surrounding medium in dictating the ablation dynamics. Notably, liquid environments, such as water and glycerin were found to not only enhance cooling effects but also facilitate the formation of larger ablation craters due to plasma confinement and alterations in laser beam spot size related to refractive index changes. The determination of the laser fluence threshold and the systematic evaluation of ablation crater diameters were instrumental in refining the laser ablation process. The outcomes of this research provide valuable insights into the precise control of PLAL conditions for the efficient production of silicon nanoparticles in various solutions, emphasizing the technique’s adaptability, and potential in advancing the fields of nanotechnology and materials science. © 2024 IAMOT
