Local Thermodynamic Equilibrium in Laser-Induced Breakdown Spectroscopy: Beyond the McWhirter criterion
Abstract In the Laser-Induced Breakdown Spectroscopy (LIBS) technique, the existence of Local Thermodynamic Equilibrium (LTE) is the essential requisite for meaningful application of theoreticalExpand
From single pulse to double pulse ns-Laser Induced Breakdown Spectroscopy under water: Elemental analysis of aqueous solutions and submerged solid samples
Abstract In this paper the developments of Laser Induced Breakdown Spectroscopy (LIBS) underwater have been reviewed to clear up the basic aspects of this technique as well as the main peculiaritiesExpand
Nanoparticle-enhanced laser-induced breakdown spectroscopy of metallic samples.
In this article, an increase of 1-2 orders of magnitude in laser-induced breakdown spectroscopy (LIBS) signals was obtained by depositing silver nanoparticles on metal samples. Nanoparticle-enhancedExpand
Experimental and theoretical comparison of single-pulse and double-pulse laser induced breakdown spectroscopy on metallic samples
In this paper, single pulse (SP)- and double pulse (DP)- Laser Induced Breakdown Spectroscopy (LIBS) on metallic titanium, aluminum-based alloy and copper-based alloy have been studied by spectrallyExpand
Double-pulse LIBS in bulk water and on submerged bronze samples
In this work laser-induced breakdown spectroscopy (LIBS) has been applied in bulk water using a double-pulse laser source. As in the case of former experiments in air, the use of the double-pulseExpand
Double pulse laser produced plasma on metallic target in seawater: basic aspects and analytical approach
In this work, laser-induced breakdown spectroscopy has been applied in seawater using a dual pulse laser source. Fundamental aspects of laser-induced plasma under water as well as the effects of theExpand
ns- and fs-LIBS of copper-based-alloys: A different approach
Abstract A self-calibrated analytical technique, based on plasmas induced by either 250 fs or 7 ns laser pulses, is presented. This approach is comparable to other calibration-free methods based onExpand
Effects of the background environment on formation, evolution and emission spectra of laser-induced plasmas
Abstract In this paper the most important features of Laser Induced Plasma (LIP) evolution were analyzed from the fundamental point of view, in order to point out the effects of backgroundExpand
Multi-methodological investigation of kunzite, hiddenite, alexandrite, elbaite and topaz, based on laser-induced breakdown spectroscopy and conventional analytical techniques for supporting
Gem-quality alexandrite, hiddenite and kunzite, elbaite and topaz minerals were characterized through a multi-methodological investigation based on EMPA-WDS, LA-ICP-MS, and laser-induced breakdownExpand
Heavy metal concentrations in soils as determined by laser-induced breakdown spectroscopy (LIBS), with special emphasis on chromium.
Soil is unanimously considered as one of the most important sink of heavy metals released by human activities. Heavy metal analysis of natural and polluted soils is generally conducted by the use ofExpand
