Fluorescence quenching of coumarins by halide ions
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2004Fluorescence quenching of 4-methyl-7-methoxy coumarin (1) and 4-methyl-5-ethoxy-7-methoxy coumarin (2) in aqueous solutions have been studied at different concentrations of halide ions (Cl-, Br-, I-), at room temperature approximately 20 degrees C. It is observed that the fluorescence intensity of both the coumarin compounds (1 and 2) decrease with ...

Concentration Quenching of Nd^3+ Fluorescence
Applied Optics, 1968Concentration quenching of the 1.06-micro Nd(3+) fluorescence in glass is investigated to help determine the nature of the Nd(3+)-Nd(3+) interaction that causes quenching. The relative fluorescent efficiency vs Nd(3+) concentration is measured for thin, polished plates of glass in an apparatus designed to minimize instrumental distortion of the ...

Fluorescence Quenching Reactions
1991The quenching of the fluorescence of biomacromolecules by solute quenchers has become a widely used and powerful technique (Lehrer, 1976; Lehrer and Leavis, 1989; Lakowicz, 1983; Eftink and Ghiron, 1981; Eftink, 1991). Such quenching reactions have been used primarily to obtain topographical information about proteins, nucleic acids, and membrane ...
