摘要：

In order to reveal the generation mechanistic of laser-induced breakdown spectroscopy characteristic difference between liquid and solid matrices, spatial evolution characteristics of Cr-element emission spectra, electron temperature, and electron density of the plasma generated via the pulsed laser ablation of a CrCl3 aqueous solution using liquid jet sampling technology are investigated. Results show that the laser-induced plasma in the liquid matrix has distinctly different spatial evolution characteristics compared with that in the solid matrix. Along the direction of the laser beam, the plasma can expand up to 0.8 mm away from the jet surface and the plasma plume has a small linear diameter of approximate 3.2 mm. Further, the maximum intensities of ionic and atomic spectral lines appear 0.8 mm and 0.4 mm away from the jet surface, respectively. Simultaneously, the electron temperature and electron density of the plasma are small and slightly vary within 2939-3611 K and (0.0149-4.86)×1014 cm3, respectively, along the laser beam direction. Maximum values are observed at 0.8 mm away from the jet surface. Similar to the solid-matrix plasma, the spatial evolution characteristics of plasma emission spectra, electron temperature, and electron density of the liquid-matrix plasma have good spatial symmetry. © 2019, Chinese Lasers Press.
