Quantitative determination of fluoride in pure water using luminescent europium complexes

Quantitative determination of fluoride in pure water using luminescent europium complexes.

Two luminescent probes [Eu.L¹⁻²]⁺ are reported for the rapid detection of fluoride in water. Probes [Eu.L¹⁻²]⁺ exhibit exceptional enhancements in Eu emission in the presence of fluoride, permitting its selective determination within the environmentally relevant concentration range (20-210 μM).

Quantitative determination of uoride in pure water using luminescent europium complexes

Synthesis of luminescent europium defects in diamond.

Lanthanides are vital components in lighting, imaging technologies and future quantum memory applications owing to their narrow optical transitions and long spin coherence times. Recently, diamond has become a pre-eminent platform for the realisation of many experiments in quantum information science. Here we demonstrate a promising approach to incorporate Eu ions into diamond, providing a mean...

Luminescent Properties of Europium Complexes with Different Long Chains in Langmuir-Blodgett (LB) Films

A series of europium(III) complexes with different chain length, tris [2-m-pyridylmethanamido-5-phenyl(1,3,4)-oxadiazole] mono [2-(4-n-alkylphenyl)-iminazole (4,5-f)-1,10-phenanthroline] Eu(III) [Eu(PMA)3Nn (n = 6, 10, 14,18)] were synthesized. All of these amphiphilic europium(III) complexes could form stable Langmuir film at air/water interface and could be transferred onto hydrophilic quartz...

Europium (III) Organic Complexes in Porous Boron Nitride Microfibers: Efficient Hybrid Luminescent Material

We report the design and synthesis of a novel kind of organic-inorganic hybrid material via the incorporation of europium (III) β-diketonate complexes (Eu(TTA)3, TTA = 2-thenoyltrifluoroacetone) into one-dimensional (1D) porous boron nitride (BN) microfibers. The developed Eu(TTA)3@BN hybrid composites with typical 1D fibrous morphology exhibit bright visible red-light emission on UV illuminati...
