Laser-Induced Breakdown Spectroscopy for Chemical Mapping of Materials

Abstract: Analytical techniques able to perform spatially resolved analysis are highly demanded in the surface analysis and material science fields. Compared to other analytical techniques usually employed, laser-induced breakdown spectroscopy (LIBS) offers several advantages, such as simplicity and robustness of instrumentation, which permit on-line and in situ measurements. No or minimal sample preparation is required, and the analysis of any sample without restrictions on the shape, size, or conductive nature can be performed under atmospheric conditions in a matter of seconds. In this work, a review of the different instrumental approaches employed in the generation of compositional maps as well as a detailed discussion of the different applications that involve the use of LIBS to obtain two-dimensional or even three-dimensional chemical maps is presented.
