“…[207][208][209] In ICP work, Doidge 210 reported branching ratios for the elements Fe, Se, Te, Ge, and Pd. A detailed description of the relative and absolute calibration procedure of a broad band echelle spectrometer has been recently described by Bibinov et al 211,212 In LIBS work, using an echelle spectrometer, Rehse and Ryder 213 have measured the branching ratio from hundreds of transitions of singly ionized Nd and Ga, although the focus of the work was not the calibration of the system.…”

Laser-induced breakdown spectroscopy (LIBS) has become a very popular analytical method in the last decade in view of some of its unique features such as applicability to any type of sample, practically no sample preparation, remote sensing capability, and speed of analysis. The technique has a remarkably wide applicability in many fields, and the number of applications is still growing. From an analytical point of view, the quantitative aspects of LIBS may be considered its Achilles' heel, first due to the complex nature of the laser–sample interaction processes, which depend upon both the laser characteristics and the sample material properties, and second due to the plasma–particle interaction processes, which are space and time dependent. Together, these may cause undesirable matrix effects. Ways of alleviating these problems rely upon the description of the plasma excitation-ionization processes through the use of classical equilibrium relations and therefore on the assumption that the laser-induced plasma is in local thermodynamic equilibrium (LTE). Even in this case, the transient nature of the plasma and its spatial inhomogeneity need to be considered and overcome in order to justify the theoretical assumptions made. This first article focuses on the basic diagnostics aspects and presents a review of the past and recent LIBS literature pertinent to this topic. Previous research on non-laser-based plasma literature, and the resulting knowledge, is also emphasized. The aim is, on one hand, to make the readers aware of such knowledge and on the other hand to trigger the interest of the LIBS community, as well as the larger analytical plasma community, in attempting some diagnostic approaches that have not yet been fully exploited in LIBS.

“…The produced ablation plume was subsequently intersected with a probe beam from a tunable dye laser (Sirah, Cobra-Stretch, DCM dye) that was equipped with a harmonic generator (BBO) and was pumped by A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT 5 another Nd:YAG laser (Spectra Physics, INDI-10). The UV probe beam was first expanded with a quartz concave lens (focal length: −250 mm) and then converted into a thin sheet-shaped beam by passing through a slit (gap width: 0.5 mm) located in front of the sample to avoid generating interference fringes.…”

“…LIBS for the detection of gadolinium in molten glass, in coated stainless steel plates, and in its oxide form have been reported in References [15][16][17]. Lanthanum in molten glass and alloys of neodymium have also been reported [15,[18][19][20][21][22]. Studies to detect samarium as a trace pollutant in soils, and its alloys using the LIBS technique have been published [23,24].…”

Micro-Laser-Induced Breakdown Spectroscopy: A Novel Approach Used in the Detection of Six Rare Earths and One Transition Metal

et al. 2019

Laser-induced breakdown spectroscopy (LIBS) was undertaken using an instrument which used a high-powered microscope to deliver the light and tightly focused the low energy laser beam onto the surface of a solid sample. A micro-plasma was generated on the surface of the sample under test even though the amount of energy/pulse from a beam of 532 nm was <1 mJ. Rare earth elements such as europium, gadolinium, lanthanum, neodymium, praseodymium, samarium, and a transition metal, yttrium, were tested. These elements are important in nuclear fission reactions especially for estimation of actinide masses for non-proliferation “safeguards”. Each element was mixed in the graphite matrix in different percentages from 1% to 50% by weight and the LIBS spectra were obtained for each composition as well as after mixing each element in the same amount using oxides of the elements. The data for the 5% mixture of the rare earth elements with graphite powder along with the transition metal has been presented in this article. A micro-LIBS approach was used to demonstrate that these rare earth elements can be identified individually and in a complex mixture in glove boxes in which the microscope LIBS instrument is housed in a nuclear research environment.
