Synthesis of silicon nanoparticles by picosecond laser ablation in liquid

Abstract

Silicon-based nanoparticles were produced by irradiating a single crystal silicon target in de-ionized water with Nd:YAG laser at wavelengths of 1064 nm. The main goal of our work presented here was enlight the role of thermal effects on the process of laser ablation of solid target in liquid. The additional heating of the target surface by continuous laser was applied during the experiment. The shift of NPs size distribution caused by applying of additional continuous laser was reported in this work.
