Crystal structures and luminescence properties of [Eu(ODA)·(phen)·4H2O]+, [Tb(ODA)·(phen)·4H2O]+ and [Tb(ODA)3]3− (ODA: oxydiacetate, phen: 1,10-phenanthroline)

Photophysical Properties of Eu(III) Center Covalently Immobilized in Si‐O‐B and Si‐O‐Ti Composite Gels

“…Further, we determined the emission quantum efficiencies of the 5 D 0 europium ion excited state for Eu 3+ hybrid gel on the basis of the emission spectra and lifetimes of the 5 D 0 emitting level using four main equations (37–43). The detailed principle and method was adopted from Ferreira et al.…”

“…(37) and the data are shown in Table 1. Here A 0 J is the experimental coefficients of spontaneous emissions ( J = 0, 1, 2, 3, 4) for the branching ratio for the 5 D 0 → 7 F 5, 6 transitions can be neglected as they both are not detected experimentally, whose influence can be ignored in the depopulation of the 5 D 0 excited state (37–43). A 01 is the Einstein’s coefficient of spontaneous emission between the 5 D 0 and 7 F 1 energy levels.…”

Crystal structure of bis[triaqua(oxydiacetato-k3O,O′,O″)copper(II)] trihydrate, [Cu(C4H4O5)(H2O)3]2 · 3H2O

“…One example of an acid that contains two carboxylic groups is oxydiacetic acid (H 2oda). Agreat number of metal complexes based on H 2 oda with some important features have been reported [2][3][4]. The asymmetric unit of the title complex is comprised of two halfmolecules of the mononuclear Cu II complex and three water mol- [5,6], in which the oda shows chelate bridging m 3 coordination pattern.…”

Crystal structure of catena-poly[(μ2-4,4′-bipyridine-κ2N:N′)-tetraqua-cobalt(II)] – (3-(carboxylatomethyl)benzoic acid) – water (1/2/2), C28H34CoN2O14

“…For instance, a exible aromatic acid that contains two carboxylic groups is 3-(carboxymethyl)benzoic acid (H 2 cmb). Surprisingly, its metal complexes are seldom reported [2] and perhaps the proper synthesis conditions are not easy to obtain. In this paper, we describe a Co II compound con- (Fig.).…”
