TLDR
In this paper, the applicability of the well-known Judd-Ofelt theory to the emissive properties of Eu3+ complexes is investigated, and it is demonstrated experimentally that the radiative lifetime of the 5D0 excited state of the Eu 3+ can be calculated directly from its corrected emission spectrum, without using Judd-ofelt theory.Abstract:
Although luminescent complexes of lanthanide ions and organic ligands have been studied intensively, relatively little attention has been paid to the natural (or ‘radiative’) lifetime of the lanthanide centered luminescent state in these systems. Here, the applicability of the well-known Judd–Ofelt theory to the emissive properties of Eu3+ complexes is investigated. Moreover, it is demonstrated experimentally that the radiative lifetime of the 5D0 excited state of Eu3+ can be calculated directly from its corrected emission spectrum, without using Judd–Ofelt theory. We also discuss briefly the possibility of finding the natural lifetimes of lanthanide ions other than Eu3+.read more

Taking advantage of luminescent lanthanide ions
TL;DR: This critical review has been tailored for a broad audience of chemists, biochemists and materials scientists; the basics of lanthanide photophysics are highlighted together with the synthetic strategies used to insert these ions into mono- and polymetallic molecular edifices.

Lanthanide luminescence for functional materials and bio-sciences
TL;DR: This critical review describes the latest developments in the sensitization of near-infrared luminescence, "soft" luminescent materials (liquid crystals, ionic liquids, ionogels), electroluminescentmaterials for organic light emitting diodes, with emphasis on white light generation, and applications in luminecent bio-sensing and bio-imaging based on time-resolved detection and multiphoton excitation.

Lanthanide Luminescence for Biomedical Analyses and Imaging
TL;DR: This data indicates that the prostate-Specific antigen in the europium-Tetracycline complex acts as a ‘spatially aggregating force’ to form terbium complexes in the Optical Probes.

Interpretation of europium(III) spectra
TL;DR: The trivalent europium ion (Eu3+) is well known for its strong luminescence in the red spectral region, but this ion is also interesting from a theoretical point of view as mentioned in this paper.

TL;DR: In this paper, the authors derived a modified 1/τ0=2.880×10−9n2/n2-1(gl/gu) ∫ edlnν, which should be valid for broad molecular bands when the transition is strongly allowed.
