Energy transfer between 1,3-dimethylxanthine and europium(III) in aqueous solution

Ligand-sensitized fluorescence of Eu3+ using naphthalene carboxylic acids as ligands

“…The fluorescence of these lanthanides has been shown to be enhanced by ligand sensitization with appropriately chosen ligands [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. In these experiments, the lanthanide ion is complexed to a ligand; the ligand is then optically excited, followed by an efficient energy transfer from the strongly absorbing ligand to the rather poorly absorbing lanthanide ion.…”

Photoluminescence enhancement of Sm3+ in the Sm3+–salicylic acid–o-phenanthroline ternary composite

“…The fluorescence enhancement has generally been achieved through ligand sensitization [1][2][3]. In this process, an organic ligand is first excited by light absorption, followed by energy transfer from the ligand to the excited levels of a lanthanide.…”

Liquid Chromatographic Determination Using Lanthanides as Time-Resolved Luminescence Probes for Drugs and Xenobiotics: Advantages and Limitations

“…28 Further alkalinization causes precipitation of lanthanide hydroxide. [11][12][13][14][15]27,28 Perry and Winefordner 29,30 reported that TRIS buffer was likely to have chelating properties towards Ln 3+ and thus prevent the quenching effect of water on lanthanide luminescence. However, in our experiments 8,9 using diluted NaOH instead of TRIS buffer to adjust the pH to 7.4, we observed a similar enhancement of Tb 3+ luminescence.…”
