LIBS spectra were obtained for 20 alkali halides using a hand-held instrument. The intensities of the strongest emission lines were determined for Li, Na, K, Rb, Cs, F, Cl, Br, and I, and their corresponding electronic transitions assigned. Halogen peak intensities are observed to be at least two orders of magnitude smaller than those of the alkali metals. Thus, halogens are difficult to detect and identify with certainty. Relative intensity ratios of halogen/alkali metal aid in identification of those nonmetals, particularly in mineralogical samples.

碱卤化物 Libs 发射光谱的相对强度测量及其在矿物样品元素分析中的应用

使用手持仪器获得了 20 种碱金属卤化物的 LIBS 光谱。最强发射线的强度由 Li、Na、K、Rb、Cs、F、Cl、Br 和 I 确定，并指定了它们相应的电子跃迁。观察到卤素峰强度比碱金属的峰强度小至少两个数量级。因此，卤素很难被确定地检测和识别。卤素/碱金属的相对强度比有助于识别这些非金属，特别是在矿物样品中。
