Influence of applying the additional continuous laser on photoluminescence properties of silicon nanoparticles produced by 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 continuous laser was applied immediately prior and during the ablation. The noticeable shift of nanoparticle size distribution caused by using the additional continuous laser was reported. In the paper we focused our attention at the photoluminescence properties on nanoparticles produced by LAL when the additional continuous laser was employed.
