Spectroscopic study of lanthanide squarate hydrates
(1994-12-01)
In the present investigation some spectroscopic properties of several lanthanide squarate hydrates are reported. The Raman spectra show the same distinctive Jahn-Teller intensity pattern for non-totally symmetric modes, ...

Estudo do comportamento térmico e da luminescência de filmes de quitosana com os íons Eu3+ e Tb3+
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2007-08-30)
Films of chitosan with trivalent lanthanides ions Eu3+ and Tb3+ were respectively prepared in the ratio of 3:1 m/m (chitosan: lanthanide) and 6:1 m/m (chitosan: lanthanide). There were no formations of films in a ratio of ...
Spectroscopic, luminescence and in vitro biological studies of solid ketoprofen of heavier trivalent lanthanides and yttrium(III)
(Elsevier B.V., 2014-11-01)
Solid-state compounds of the general formulae [ML3] (M = Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y; L = ketoprofen) were synthesized and characterized using infrared, diffuse reflectance and luminescence spectroscopies. IR data ...
A thermal behaviour study of solid-state cinnamates of the latter trivalent lanthanides and yttrium(III)
(2003-03-05)
Some new compounds of cinnamic acid with the latter trivalent lanthanides and yttrium(III) were synthesized in the solid state. The compounds have the general formula LnL3, where Ln represents trivalent Eu to Lu or Y ions ...

Study of the binding of Eu3+ and Tb3+ to L-phenylalanine and L-tryptophan
(1997-12-01)
Trivalent europium and terbium ions have ionic radii similar to that of Ca2+. So they are employed as probes of calcium binding sites in biological molecules. These ions exhibit very useful spectroscopic characteristics, ...

Lanthanides-clay nanocomposites: Synthesis, characterization and optical properties
(2009)
Complexes of Europium(III) and Terbium(III) with 2,2-bipyridine and 1,10-phenanthroline were inserted into Na-bentonite by ion exchange reactions at room temperature. The products display interlaminar distances and ...
