The effect of ligand conjugation length on europium complex performance in light-emitting diodes

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

“…The O-H vibrations are also effective quenchers of lanthanide luminescence [16,23]. Other vibrations commonly found in organic molecules have important contributions to k nr [24]. The fluorescence lifetimes of the four europium complexes in DMF solution are analyzed assuming monoexponential decay kinetics.…”

Preparation and photoluminescence of some europium (III) ternary complexes with β-diketone and nitrogen heterocyclic ligands

“…Since Kido reported the europium (III) complex-based electroluminescence devices in 1991 [1], many Europium complexes with various b-diketones as ligands have received great interest due to their characteristic luminescence properties and extremely sharp, intense emission in the visible region [2][3][4]. This kind of complexes has promising applications in material science such as sensory materials [5], electroluminescent materials [6], laser materials [7] and luminescent probe [8].…”

Photo- and electroluminescent behavior of Eu3+ ions in blends with poly(vinyl-carbazole)

“…2,3,5 The interaction of Eu 3+ ions with organic molecules and derived complexes have been well studied. The behavior of the ion in relation to polymer chains has been addressed by some authors, [6][7][8][9][10] particularly when solution and solid state properties are involved. Intramolecular energy transfer in lanthanide coordination compounds and their use in electroluminescent devices have been recently explored.…”
