Abstract
Two new europium complexes, Eu(NTA)3(bath) and Eu(NTA)3(DPEPO), were synthesized and characterized by elemental analysis, Fourier transform infrared, mass spectrometry, thermogravimetric analysis and photoluminescence spectroscopy. The room-temperature photoluminescence spectra of the Eu3+ complexes are composed of the typical Eu3+ red emission, assigned to transitions between the first excited state (5Δ0) and the multiplet (7F0-4). The results demonstrate that the substitution of water molecules by bidentate oxygen or nitrogen ligands in Eu(NTA)3(H2O)2 richly enhances the overall quantum yield (Φoverall = 12% vs. 87%) and life time values (τobs = 339 vs. 521 μs).
