Abstract In this paper a review of different approaches for handling the self-absorption effect in Laser-Induced Breakdown Spectroscopy (LIBS) applications is presented. From an analytical point of view, self-absorption is a major issue affecting the accuracy of LIBS quantitative analysis. Self-absorption impacts emission line profiles and intensities, resulting in non-linear calibration curves and influencing the estimation of the sample composition. The main purpose of this work is presenting a summary of the experimental parameters giving raise to self-absorption and a thorough study of the different strategies for its estimation, compensation and exploitation in order to improve the analytical accuracy of the LIBS technique.

评估、补偿和利用激光诱导击穿光谱自吸收的当前分析方法综述

摘要 本文综述了在激光诱导击穿光谱 (LIBS) 应用中处理自吸收效应的不同方法。从分析的角度来看，自吸收是影响LIBS定量分析准确性的主要问题。自吸收影响发射线轮廓和强度，导致非线性校准曲线并影响样品成分的估计。这项工作的主要目的是总结引起自吸收的实验参数，并对其估计、补偿和利用的不同策略进行深入研究，以提高 LIBS 技术的分析精度。
