稀土元素铕(Fu)的单光子共振和双光子共振激光增强电离光谱
Single photon resonance and two-photon resonance laser enhanced ionization spectrometry of rare-earth element Europium (Eu)
摘要
本文首次报道稀土元素铕(Eu)的激光增强电离光谱.用紫外可调谐激光器检测到EuI 287.779um,EnI 287·887nm,EuI 289.254nm,Eul 289.303nm,EuI 289.383nm的单光子共振激光增强光谱.用可见区可调谐染料激光器检测到EuI的双光子共振激光增强电离光谱.对铕(Eu)原子激发和离化机理进行了讨论.稀土元素铕的检测限达10ng/ml.
Abstract
Laser Enhanced Ionization (LEI) spectrometry of rareearth element Europium (Eu) is studied. Single photon resonance LEI spectrometry of EuI 287.779nm, EuI 287.887nm, EuI 289.254nm, Eul 280.303nm and EuI 289.383nm are detected by UV tunable laser and two photon resonance LEI speotrometry of EuI also are deteoed by visible tunable laser. The meohanism of excitation and ionization of Eu atoms are discussed. The detection limit of the element Eu is about 10 ng/ml.
