Synthesis, characterization and thermal behaviour of heavy trivalent lanthanide malonates
(Editora Unesp, 2010-01-01)
Compostos Ln-L no estado sólido, em que Ln representa os lantanídeos trivalentes (Tb - Lu) e L é malonato, foram sintetizados neste trabalho. A termogravimetria e análise térmica diferencial simultânea (TG-DTA), calorimetria ...
Luminescence and non-radiative processes in lanthanide squarate hydrates
(1996-11-01)
The luminescence properties of solid hydrated lanthanide squarates (Ln2(C4O4)3(H2O) x; x = 8 or 13;Ln3+ = Gd, La, Eu, Tb, Pr) are reported for temperatures down to 4.2K. The luminescence of the squarate group is observed ...
