Laser-Induced Breakdown Spectroscopy (LIBS), Part I: Review of Basic Diagnostics and Plasma–Particle Interactions: Still-Challenging Issues Within the Analytical Plasma Community
David W. Hahn,Nicoló Omenetto +1 more
TL;DR: Basic diagnostics aspects of laser-induced breakdown spectroscopy are focused on and a review of the past and recent LIBS literature pertinent to this topic is presented and previous research on non-laser-based plasma literature, and the resulting knowledge, is emphasized.

Highly sensitive analysis of boron and lithium in aqueous solution using dual-pulse laser-induced breakdown spectroscopy.
TL;DR: The sensitivity for detecting boron by excitation of laminar liquid jet was found to be excellent and very practical for the online elemental analysis of boric acid and lithium hydroxide serving as neutron absorber and pH controller in the primary coolant water of pressurized water reactors, respectively.

Quantification of rare earth elements using laser-induced breakdown spectroscopy
TL;DR: In this paper, the optical emission as a function of concentration of laser-ablated yttrium (Y) and of six rare earth elements, europium (Eu), gadolinium (Gd), lanthanum (La), praseodymium (Pr), NE and samarium (Sm), has been evaluated using the laser-induced breakdown spectroscopy (LIBS) technique.
Journal ArticleDOI
Determination of Rare Earth Elements in Geological Samples Using Laser-Induced Breakdown Spectroscopy (LIBS).
TL;DR: Analysis of unknown samples indicated that the prediction results of these samples were found comparable to those obtained by inductively coupled plasma mass spectrometry analysis, suggesting that LIBS has potential to quantify REEs in geological minerals/ores.

Ablation plume structure and dynamics in ambient gas observed by laser-induced fluorescence imaging spectroscopy
TL;DR: In this article, the second harmonic beam from an Nd:YAG laser was focused on a sintered oxide pellet or a metal chip of gadolinium, and the produced plume was subsequently intersected with a sheet-shaped UV beam from a dye laser so that time-resolved fluorescence images were acquired with an intensified CCD camera.
