为了阐明格林辉光放电等离子体中IIIB族元素的光谱特征，研究了使用不同等离子体气体（即氩、氖、氩-氦和氖-氦）时它们在160-800 nm波长范围内的发射线的相对强度并制成表格。辉光放电光源的特征是观察到的发射光谱强烈依赖于所使用的等离子气体的类型。当使用氖气而不是氩气作为等离子气体时，观察到极强的离子线。此外，仅在含氦等离子体中才能观察到不同组的离子线。这些离子线的激发主要归因于分析物原子和等离子体气体离子之间的电荷转移碰撞。
In order to clarify the spectroscopic characteristics of the Group IIIB elements in Grimm glow discharge plasmas, the relative intensities of their emission lines in the wavelength range 160–800 nm were investigated and tabulated when using different plasma gases, viz., argon, neon, argon–helium and neon–helium. It was characteristic of the glow discharge light source that the emission spectra observed were strongly dependent on the type of plasma gas employed. Extremely intense ionic lines were observed when neon rather than argon was employed as the plasma gas. Furthermore, different groups of ionic lines could be observed only in the helium-containing plasmas. The excitation of these ionic lines can be principally attributed to charge-transfer collisions between the analyte atoms and the plasma gas ions.
