advantages include better spectral resolution due to large Stokes shifts and narrow emission lines and increased temporal resolu ...

Almost as important as the choice of lanthanide is the choice of ancillary ligand, which transforms the lanthanide into a recep- ...

lanthanide luminescence lies in nonradiative deactivation or relaxation due to solvent interactions, which can reduce emission i ...

Another concern is that, for a 9-coordinate lanthanide ion in aqueous solution bound to a single tridentate DPA ligand, the six ...

Luminescence lifetime measurements were performed, and the decay curves fit to a monoexponential model to obtain the lifetime of ...

Evidence for this“enhanced receptor effect”can be found for var- ious other lanthanide/ligand/analyte systems by comparing repor ...

binding affinity that does not track with lanthanide ionic radius, with the greatest difference between terbium and europium. Th ...

species in the former case would reduce the overall binding affin- ity due to a decrease in electrostatic attraction to the dipo ...

the fact that the Tb^4 þion has an electronic configuration with an exactly half-filled 4f-shell( 5 ). As a result, this lanthan ...

ligand-induced enhancement is lanthanide dependent and is governed by the gadolinium break. We believe this property is due to a ...

We explored three common CAs—DA, Epi, and NE—along with Cat as a control species. Excitation spectra of the Tb(ligand) (CA) comp ...
