Synergistic Luminescence Effect and Its Analytical Application

Abstract

Abstract: A new sensitized fluorescence phenomenon was observed by adding some of metal ions to Eu (Sm)-DBM-CPB or Eu(Sm)-TTA-Phen-Triton X-100 system, which is known as a synergistic luminescence effect. The synergistic luminescence effect and its analytical application were studied using laser-induced fluorimetry. The influence of the chemical properties of rare earth ions on the synergistic luminescent effects of above systems is reported. The synergistic luminescence systems can be used for the determination of ultratrace amounts of europium and samarium. Results are satisfactory for the determination of trace europium and samarium in highly pure rare earth oxides and synthetic samples.

Key words: Synergistic luminescent effect, Fluorimetry, Rare earths analysis
