This study focuses on the analysis of the optical emission response obtained by laser-induced breakdown spectroscopy from energetic nitro compounds in condensed phase sampled in atmospheres of variable composition. The influence of different background gases was evaluated from the characteristic emissions of the excited species coexisting in the plasma plume and conclusions concerning the main pathways involved in the generation of such emission species were extracted. Different reactive (O2, N2, H2) and inert (Ar, He) gases were tested to establish the comparative emission features of organic compounds.
本研究聚焦于对激光诱导击穿光谱法从可变组成气氛中采样的凝聚相高能硝基化合物获得的光发射响应进行分析。通过等离子体羽流中共存的激发态物种的特征发射来评估不同背景气体的影响，并提取有关此类发射物种产生所涉及的主要途径的结论。测试了不同的反应性气体（O₂、N₂、H₂）和惰性气体（Ar、He），以确定有机化合物的比较发射特征。
