The role of target warming in the 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 additional heating of the target by continuous laser was applied during the experiment and the targets that differ in volume, were used. In the work presented here we further investigated the role of thermal effects, such as warming of the target, on the LAL process. The noticeable shift of NPs size distribution caused by using the targets of different volumes was reported.
