| 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. |
