Laser-Induced Breakdown Spectroscopy Imaging for Material and Biomedical Applications: Recent Advances and Future Perspectives

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…The techniques of XRD (for crystal structure), SEM and FTIR were also used for characterisation. The TOF-SIMS results showed the presence of over-lithiated grains of diameter 400 ± 100 nm and nanoparticles of diameter 100 ± 30 nm with an increased 7 Li 16 O + content in the buried part of the lm. It was thought that these Li-rich areas could possibly be used as Li reservoirs to compensate for lithium losses during fabrication and cell operation.…”

“…Another review, entitled “ Laser induced breakdown spectroscopy imaging for material and biomedical applications: recent advances and future perspectives ” with 160 references was presented by Gardette et al 7 The “imaging” part of the title indicates that the review focusses on the 2-dimensional surface mapping of samples rather than bulk analysis. This paper also gave an overview of the requirements of the system (laser types, focussing elements, spectrometers, detectors, etc.…”

Measurement of transient temperature using laser-induced breakdown spectroscopy (LIBS) with the surface temperature effect

“…Laser-induced breakdown spectroscopy (LIBS) is a qualitative/quantitative technology that analyzes plasma radiation spectra and is applicable for detecting solids, liquids, and gases. 20,21 With real-time, in situ, non-destructive, and noncontact characteristics, LIBS has been widely used in material analysis, defect detection, and other elds. [22][23][24][25][26][27] Due to the ultrashort pulse width of the laser (on the order of fs to ns), ultrahigh time resolution of the spectrometer ($2 ns), and extremely small ablation spot (on the order of mm), LIBS is well suited for measuring physical quantities in high-speed processes.…”

Detection of tritium using ultrafast laser-induced breakdown spectroscopy

“…In particular, when an ultrafast laser is used for ablation, improved spatial mapping and precision depth proling capabilities can result, owing to its limited heat-affected zone in comparison to nanosecond pulsed lasers. 2,21 One of the challenges associated with LIBS for isotopic analysis of light elements is the line broadening. LIBS requires thermal excitation which happens only at early times of laserproduced plasma evolution where various plasma broadening mechanisms dominate.…”
