Photophysical properties of a series of high luminescent europium complexes with fluorinated ligands

Semiconducting Polymer Dots Doped with Europium Complexes Showing Ultranarrow Emission and Long Luminescence Lifetime for Time‐Gated Cellular Imaging

“…Europium (Eu) complexes Eu15F and EuDNM were synthesized in the lab as reported earlier. [15, 27] 300-nm nanoparticles with red fluorescence (R300 NPs) were purchased from Thermo Scientific (IL, USA). Eu-complex/PVK Pdot preparation, conjugation and flow cytometry experiments are described in more detail in supplementary materials.…”

“…The luminescence lifetime data of PVK Pdots and PVK Pdots doped with Eu complex were obtained with a Lecroy Wave Runner 6100 digital oscilloscope (1 GHz) using the excitation of a third harmonic (355 nm) of a Nd:YAG laser (pulse width of 6 ns). [27] The lifetime of R300 NPs was measured by using a PicoQuant Fluorescence lifetime system (PicoQuant Photonics North America Inc. Westfield, MA USA). [6] A Nikon TE2000 inverted microscope was modified for timegated fluorescence image collection.…”

New Fluorescent Hybrid Materials Based on Eu-Complexes in Oxyfluoride Glass and Glass-Ceramic Matrix

“…Different methods of preparation of europium (III) complexes have been described [7][8]. Syntheses of organic ligands were carried out according to a slightly modified procedure [9][10] using dichloromethane as a solvent.…”

Synthesis, photoluminescent features and intramolecular energy transfer mechanism of europium (III) complexes with fluorinate β-diketone ligand and auxiliary ligands

“…The fluorine substituents on the ligand enhance the spin-orbit coupling via heavy atom effect confirmingly promoting the intersystem crossing (ISC) [14][15][16][17]. To achieve the above objective, a new b-diketonate ligand DPBD was synthesized by an ecofriendly microwave method which embodied with fluorinated alkyl group as well as conjugated phenyl group employing as 'antenna' for europium ion to effectively photosensitize its emission [18].…”
