Effects of Zinc(II) on the Luminescence of Europium(III) in Complexes Containing β‐Diketone and Schiff Bases

Abstract

Dedicated to Professor Jean-Claude Bünzli on the occasion of his 65th birthdayThe UV, excitation, and luminescence spectra of tris(pivaloyltrifluoroacetonato)europium(III) ([Eu(pta) 3 ]; Hpta ¼ 1,1,1-trifluoro-5,5-dimethylhexane-2,4-dione ¼ HA) were measured in the presence of bis(salicylidene)trimethylenediamine (H 2 saltn), bis [5-(tert-butyl)

Recent advances in 1,10-phenanthroline ligands for chemosensing of cations and anions

“…Based on the fact that the introduction of appropriate amounts of Zn 2+ in Ln-Schiff base complexes could enhance the luminescence of the lanthanide complexes, [91][92][93][94] Zhou et al synthesized two such Eu 2+ -complexes (51a and 51b) 95 determination of trace amounts of Eu 3+ and Zn 2+ . Based on this, the trace amounts of Eu 3+ was determined in synthetic rare earth oxide mixture and high purity La 2 O 3 matrix while that of Zn 2+ in high purity Mg(NO 3 )2.6H 2 O matrix, hence, ascertaining the practical applicability of the system.…”
