چکیده

The nonradiative deactivation of the excited state of europium(III)-based phosphors via OH-vibrations in the presence of water allows the detection of moisture in nitrogen at concentration levels down to at least 25 ppm (0.09% RH).

Rare Earth Nitrate Complexes with an ONO Schiff Base Ligand: Spectral, Thermal, Luminescence and Biological Studies

Five rare earth complexeslanthanum(III),praseodymium(III),neodymium(III), samarium(III) and europium(III) have been synthesized from Schiff base ligand (N,N-bis (2-hydroxy-1-naphthylidene) acetylhydrazone). The complexes were characterized based on elemental analysis, molar conductance, ultraviolet, infrared, mass, thermogravimetric and powder X-ray diffraction studies. Infrared spectra sug...

Enhanced energy transfer efficiency and stability of europium β-diketonate complex in ionic liquid-based lyotropic liquid crystals.

Luminescent materials from europium β-diketonate complex in ionic liquids (ILs) could achieve enhanced luminescence efficiencies and photostabilities. However, the question of how to provide a feasible and environmentally-friendly way to distribute these lanthanide complexes uniformly and stably within IL-based matrix remains a significant challenge. Here, a soft luminescent material from IL-me...

Crystal Structure and Spectroscopic Characterization of a Luminescent Europium Chelate

We report the crystal structure at 1 Å resolution of europium bound to diethylenetriaminepentaacetate covalently coupled to an organic chromophore, carbostyril 124 (DTPA-cs124; carbostyril 124 ) 7-amino-4-methyl-2(1H)quinolinone). The complex is highly luminescent in solution and in the crystal form. The Eu-DTPA-cs124 crystallizes in the space group C2/c with two molecules in the asymmetric uni...

Spectrofluorimetric determination of trace amounts of europium(III) ion with lutetium(III)-sparfloxacin-sodium dodecyl sulfate luminescence enhancement system.

A new luminescence-enhancement system based on complex formation between europium and sparfloxacin in the presence of lutetium in a sodium dodecyl sulfate solution has been discovered. By adding a suitable amount of Lu3+ to the Eu-sparfloxacin-sodium dodecyl sulfate system, the luminescence can be enhanced by approximately 5-fold compared with that of the system without Lu3+. Under the optimum ...

Luminescence studies of lanthanide ion binding to parvalbumin.

Luminescence methods were used to examine the interaction of Eu(III) and Tb(III) with parvalbumin isozyme III from pike (Esox lucius). The bound lanthanide ions were excited both directly, via laser irradiation, and indirectly, via fluorescence energy transfer from adjacent phenylalanine residues. At high (175 microM) protein concentrations, the lanthanide titration curves exhibited pronounced ...
