Europium(III) mixed complexes with β-diketones and o-phenanthroline-N-oxide as promising light-conversion molecular devices

Abstract

The new complex tris(4,4,4-trifluoro-1-phenyl-1,3-butanedionate)(1,10-phenanthroline-N-oxide)-europium(III) shows a remarkable luminescence quantum yield at room temperature (66%) upon ligand excitation and a long ⁵D₀ lifetime (670 µs), which makes it a promising light-conversion molecular device.
