“…Under this category, the underlying purpose is either to improve the information power of the approach, i.e., by providing both molecular as well as elemental information, as in the coupling of LIBS with Raman spectroscopy, 394,,–403 or again to improve the sensitivity (laser ablation–laser-induced fluorescence, LA-LIF). 404,,–420…”

“…The determination of trace phosphorus in steel samples was described independently in two papers by Shen et al 419 and by Kondo et al 416 In the former experiment, 419 the fluorescence wavelengths were in the low UV (213.547, 213.618, and 214.915 nm) after excitation at 253.398 and 253.560 nm. Kondo et al 416 used 255.49 nm as excitation wavelength and fluorescence wavelengths at 213.618 and 214.915 nm.…”

The first part of this two-part review focused on the fundamental and diagnostics aspects of laser-induced plasmas, only touching briefly upon concepts such as sensitivity and detection limits and largely omitting any discussion of the vast panorama of the practical applications of the technique. Clearly a true LIBS community has emerged, which promises to quicken the pace of LIBS developments, applications, and implementations. With this second part, a more applied flavor is taken, and its intended goal is summarizing the current state-of-the-art of analytical LIBS, providing a contemporary snapshot of LIBS applications, and highlighting new directions in laser-induced breakdown spectroscopy, such as novel approaches, instrumental developments, and advanced use of chemometric tools. More specifically, we discuss instrumental and analytical approaches (e.g., double- and multi-pulse LIBS to improve the sensitivity), calibration-free approaches, hyphenated approaches in which techniques such as Raman and fluorescence are coupled with LIBS to increase sensitivity and information power, resonantly enhanced LIBS approaches, signal processing and optimization (e.g., signal-to-noise analysis), and finally applications. An attempt is made to provide an updated view of the role played by LIBS in the various fields, with emphasis on applications considered to be unique. We finally try to assess where LIBS is going as an analytical field, where in our opinion it should go, and what should still be done for consolidating the technique as a mature method of chemical analysis.

“…We attempted to discern the spectral characteristics of the S atom and ion, but the characteristics were not found. Spectral characteristics of P and S in the ultraviolet band are much stronger than their visible band characteristics [43,44,45]. However, an ultraviolet spectrometer requires a vacuum environment; thus, it is difficult to use in-field.…”

Sensing and mapping element distributions in plant tissues and its growth environment has great significance for understanding the uptake, transport, and accumulation of nutrients and harmful elements in plants, as well as for understanding interactions between plants and the environment. In this study, we developed a 3-dimensional elemental mapping system based on laser-induced breakdown spectroscopy that can be deployed in- field to directly measure the distribution of multiple elements in living plants as well as in the soil. Mapping is performed by a fast scanning laser, which ablates a micro volume of a sample to form a plasma. The presence and concentration of specific elements are calculated using the atomic, ionic, and molecular spectral characteristics of the plasma emission spectra. Furthermore, we mapped the pesticide residues in maize leaves after spraying to demonstrate the capacity of this method for trace elemental mapping. We also used the system to quantitatively detect the element concentrations in soil, which can be used to further understand the element transport between plants and soil. We demonstrate that this method has great potential for elemental mapping in plant tissues and soil with the advantages of 3-dimensional and multi-elemental mapping, in situ and in vivo measurement, flexible use, and low cost.

“…However, a signal improvement can also be obtained by improving the conventional LIBS system, e.g. using a resonant excitation system [18] or double pulse (DP) LIBS [17,[19][20][21][22][23][24][25][26][27][28][29][30][31][32].…”

A soil, a plant and a fertilizer sample were investigated by double-pulse (DP) laser-induced breakdown spectroscopy (LIBS) in orthogonal beam geometry using a reheating configuration. The DP-LIBS signal enhancement was evaluated with respect to the corresponding single-pulse (SP) LIBS as a function of the interpulse delay at various ablation energies. The maximum signal enhancement measured was 155-fold when low ablation energy (4 mJ) and an interpulse delay of 10 μs were used. At high laser energies (≥16 mJ) and interpulse delay of 0.6 μs, the maximum signal enhancement was up to 3-fold. The effect of excitation energies and interpulse delays on emission line intensities was discussed in the various conditions used. The emission line enhancement measured for ionic lines was always higher than that of atomic lines. Plasma excitation temperature and electron density measured as a function of interpulse delays at various ablation energies were shown to be related to the emission line intensities.
