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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
Journal ArticleDOI
Fluorescence Lifetime Measurements and Biological Imaging
TL;DR: The lifetime of a photophysical process is the time required by a population of N electronically excited molecules to be reduced by a factor of e via the loss of energy through fluorescence and other non-radiative processes and the average length of time τ is called the mean lifetime, or simply lifetime.

TL;DR: In this paper, Haas and Stein showed that the fluorescent yields of tervalent ions of Pr, Sm, Eu, Gd, Tb, Dy, and Tm in H2O and D2O, containing perchlorate ions, and isotope effects on the fluorescence are reported.

TL;DR: In this article, it was shown that the dominant mode of radiationless deactivation of a rare earth ion in solution is via loss of energy to hydrogen vibrations, and that such loss is proportional to the number of hydrogen vibrations in the local rare earth environment.
