Recently the use of nanoparticles (NPs) for enhancing Laser ablation based analytical techniques, is getting a growing interest in analytical atomic spectroscopy. This technique is based on the deposition of NPs on the sample surface before the laser irradiation. The effect of the coupling of NPs plasmon with the laser pulse allows a notable improvement of the analytical signal. In this study, different sizes of spherical gold nanoparticles (AuNPs), 10 nm, 40 nm, 60 nm and 100 nm, have been employed to clarify the role of the NPs size on the signal enhancement during Laser Induced Breakdown Spectroscopy (LIBS). Therefore, a systematic investigation of the Nanoparticle Enhanced LIBS (NELIBS) have been done by varying the key experimental parameters as NPs surface concentration, laser fluence and laser spot size. The experimental results show that improvement of the emission signal during NELIBS occurs at specific NPs surface concentration and that this critical concentration depends on the NP size. When the concentration has been optimized for each NP size, the plasmon-enhanced ablation is moderately affected by the NPs size.
