New Narrow-Band Luminescence Using Lanthanide Coordination Compounds for Light-Emitting Diodes

Abstract

SUMMARYFor ternary system, both anionic carboxylate ligand, namely, 4,4'-oxybis(benzoic acid)(H 2 oba) and different auxiliary ligand, namely, 1,10-phenanthroline(Phen), pyrazino [2,3-

The crystal structure of bis(μ2-5,7-dichloroquinolin-8-olato-κ3 N,O:O)-tetrakis(5,7-dichloroquinolin-8-olato-κ2 N,O)bis(methanol-κ1 O)dieuropium(III) — toluene (1/1), C63H39Cl12Eu2N6O8

“…Owing to its luminescent nature [18], the europium ion conjugated to bulky multi-dentate organic matrices, which are also used as bioimaging agents in biomedical sciences [19,20]. The use of organic matrices coordinated to the europium ion is primarily to induce photo-sensitization since the metal ion itself exhibits slow emission rates and low absorption coefficients [21]. The whole phenomenon of using organic chromophores to sensitize the europium ion is affectionately known as the antenna effect [22,23].…”
