Intermolecular energy transfer from Tb3+ to Eu3+ in aqueous aggregates and on the surface of human cells.

چکیده
Efficient intermolecular energy transfer from carbostyril 124-sensitized Tb(3+) to Eu(3+) in aqueous aggregates is reported. This energy transfer was also recapitulated on the cell surface of a human kidney cell line (HEK-293T) and imaged by fluorescence microscopy as an example for the applicability of this energy transfer probe for imaging in biological systems.

Tunable Luminescence in Sr2MgSi2O7:Tb3+, Eu3+Phosphors Based on Energy Transfer
A series of Tb3+, Eu3+-doped Sr2MgSi2O7 (SMSO) phosphors were synthesized by high temperature solid-state reaction. X-ray diffraction (XRD) patterns, Rietveld refinement, photoluminescence spectra (PL), and luminescence decay curves were utilized to characterize each sample's properties. Intense green emission due to Tb3+ 5D4→7F5 transition was observed in the Tb3+ single-doped SMSO sample, and...
متن کاملLayered rare-earth hydroxide and oxide nanoplates of the Y/Tb/Eu system: phase-controlled processing, structure characterization and color-tunable photoluminescence via selective excitation and efficient energy transfer
Well-crystallized (Y0.97-x Tb0.03Eu x )2(OH)5NO3·nH2O (x = 0-0.03) layered rare-earth hydroxide (LRH) nanoflakes of a pure high-hydration phase have been produced by autoclaving from the nitrate/NH4OH reaction system under the optimized conditions of 100 °C and pH ∼7.0. The flakes were then converted into (Y0.97-x Tb0.03Eu x )2O3 phosphor nanoplates with color-tunable photoluminescence. Detaile...

Submitted for the MAR06 Meeting of The American Physical Society Tunable Electronic Energy Transfer in Layered Inorganic Solids Codoped with Tb3+ and Eu3+ CHRISTIE LAROCHELLE, Franklin & Marshall College — Ln[M(CN)2]3 systems (Ln=trivalent rare earth, M=Au,Ag) have a layered structure consisting of alternating layers of the M(CN)2 ions and Ln 3+ ions. Our past studies of tunable energy transfer...
متن کاملBifurcation and Chaos in Size-Dependent NEMS Considering Surface Energy Effect and Intermolecular Interactions
The impetus of this study is to investigate the chaotic behavior of a size-dependent nano-beam with double-sided electrostatic actuation, incorporating surface energy effect and intermolecular interactions. The geometrically nonlinear beam model is based on Euler-Bernoulli beam assumption. The influence of the small-scale and the surface energy effect are modeled by implementing the consistent ...
متن کاملOrganic linkers control the thermosensitivity of the emission intensities from Tb(iii) and Eu(iii) in a chameleon polymer.
Thermometers whose emission color gradually changes with temperature are called chameleon emitters. In this study, we discuss the mechanism of the thermosensitivity of the emission color of polymers that contain two lanthanides (Ln3+), e.g., [Tb0.99Eu0.01(hfa)3(linker)] n , where the Ln3+(hfa)3 complexes (hfa: hexafluoro acetylacetonato) are connected by a phosphine oxide "linker" molecule. Fir...
