“…In this view NELIBS may be included in the category of sample treatments for LIBS [11]. The phenomenon of interest for NELIBS is related to the fact that the laser pulse can induce a coherent oscillation of the conduction electrons in NPs.…”

“…In this case, where the substrate is not conductive, the electron field emission due to the laser field enhancement can only involve the layers of substrate that are in direct contact with the deposited NPs. Therefore, thanks to the NP mediation the laser-glass coupling is made possible only at the very sample surface, and at much lower irradiance than in normal LIBS [11]. The result is that an intense plasma is generated on the glass surface, providing information about the elemental composition of the most superficial layers of the glass sample.…”

In this paper, the new approach for Laser Induced Breakdown Spectroscopy (LIBS) based on nanoparticle\ud deposition on the sample surface is reviewed from both fundamental and application points of view. The\ud case of Nanoparticle-Enhanced LIBS (NELIBS) of metal samples is used for describing and discussing the\ud main causes of the emission signal enhancement. A set of test cases is presented, which shows\ud enhancements up to 1–2 orders of magnitude obtained using NELIBS with respect to LIBS. The feasibility\ud and potential of NELIBS are also discussed for several analytical applications, including analysis of\ud metallic samples, transparent samples and aqueous solution

Due to matrix interference and sample particle size effects, some of the most important and difficult issues in laser‐induced breakdown spectroscopy (LIBS) analysis are the calibration and quantitative measurement of a complex matrix. This study proposes the use of borate fusion as an alternative sample preparation procedure for the quantitative measurement of Al, Fe, Si and Ti in bauxite by LIBS. Analytical calibration curves were made using bauxite certified reference materials (CRM), and the precision and accuracy of the methods were evaluated by analysing an additional bauxite CRM, using two different approaches: pressed powder pellets and fused glass beads. The borate fusion method was the most suitable sample preparation technique, since particle size effects and matrix interference could be minimised, obtaining better linearity on the analytical calibration curves (r2), and more accurate and more precise results for bauxite analysis.

Abstract:In this study, a new approach for Laser-induced Breakdown Spectroscopy (LIBS) with gold nanofilm (NF) deposited on sample surface was carried out by using femtosecond laser. Different materials including metallic sample, semiconductor sample and dielectric sample were tested. Strong emission enhancement was obtained on SiO 2 , ceramic and Si sample. It was found that different lines in ceramic sample had different enhancement effect, which was probably related to concentration of different substances in ceramic. The enhancement effect was found to weaken with the increase of laser fluence. Enhancement factors of about 14 for SiO 2 , 5 for ceramic and 3 for Si sample were achieved at laser fluence of 3.3 J/cm 2 , which decreased to 9 for SiO 2 , 3 for ceramic and 1.5 for Si sample at laser fluence of 8.8 J/cm 2 . The mechanism of nanofilm-enhanced LIBS (NFELIBS) was localized surface plasmon resonance, which could change the dominant photon ionization process of sample.
