Abstract A LIBS experimental set-up is designed and evaluated to obtain the spatio-temporal distribution of atomic and molecular emission signals after the ablation of samples with different amounts of Ca and F. This analysis revealed separated temporal and spatial regions that maximized the atomic and molecular emission signals, respectively. Therefore, these distributions are investigated to elucidate the origin of the CaF molecular excited species, and to evaluate the development of an optimized method for the measurement of CaF molecular signals, which are related to the concentration of F in the sample.

LIBS 中原子和分子激发物种的时空分布：对卤素测定的潜在影响

摘要 LIBS 实验装置被设计和评估以获得在烧蚀不同量 Ca 和 F 的样品后原子和分子发射信号的时空分布。该分析揭示了分离的时空区域，使原子和分子最大化。分子发射信号。因此，研究这些分布以阐明 CaF 分子激发物种的起源，并评估测量 CaF 分子信号的优化方法的开发，这些信号与样品中 F 的浓度有关。
