“…The luminescence spectra of these compounds have been reported previously, 13,14,17,19,21,24 but detailed features were not described. Time-resolved luminescence properties can provide information on the inner-sphere coordination environments of Eu(III), but have never been investigated.…”

“…There are numerous crystallographic studies on Ln(III)-aliphatic dicarboxylate frameworks owing to their potential applications in various areas, including the control of topological structures and optoelectronic devices. [12][13][14][15][16][17][18][19][20][21] Among the many possible binding modes of dicarboxylates, 15 rigid Ox ligands bind to Ln ions, producing well-dened structures wherein uniform sideon bidentate bonds (Scheme 1(a)) form stable 5-membered ring structures. 13,14 The crystal structures of Pu(III)-Ox 22 and Am(III)-Ox 23 revealed that they are isomorphous with Ln(III) complexes.…”

“…Por otra parte, se encontró que la temperatura paramagnética de Curie θ p = -4.3 K, lo cual es consistente con el aparente ordenamiento antiferromagnético por debajo de T N . Se sugiere que la interacción de superintercambio Tb 3+ -O 2− -Tb 3+ es la responsable de tal orden magnético, ya que una interacción directa entre cationes Tb 3+ es poco probable debido a la gran distancia de separación (≈8.88 Å) [264].…”

“…Sin embargo, debido a los complicados procedimientos de síntesis y a las incertidumbres estructurales derivadas de la complejación metal-ligando, los compuestos de oxalato de tierras raras han surgido como una oportuna alternativa debido a la flexibilidad y facilidad con que estos compuestos tienden a formar monocristales [80,257,258]. Una gran variedad de oxalatos de tierras raras han sido sintetizados, pero solo unos pocos informes dan cuenta de sus propie-dades luminiscentes [80,[259][260][261][262][263][264][265][266]. La alta concentración de iones activos del orden de 10 21 iones/cm 3 en cristales facilita una alta ganancia óptica y, por tanto, pueden encontrar potenciales aplicaciones en dispositivos de iluminación de estado sólido [176].…”
