dc.description.abstract | In this work we present a study of the luminescence intensity of Eu(TTA) ?xL, where TTA5thenoyltrifluoroacetonate (L denotes 3 DBSO and PTSO sulfoxides, and derivatives of 15C5 and 18C6 macrocyclics). The complexes with 15-crown-5 ether ligand contain two H O molecules. The complexes were characterized by a microanalytical procedure, IR spectroscopy and molar conductance. They show 2 31 high luminescence mainly in the red region. The characteristic emission spectra of Eu in these compounds show uncommonly high 5 7 values of the V intensity parameters, reflecting the hypersensitive behavior of the D F transition and indicating that the rare earth 2 0 2 5 7 ion is in a highly polarizable chemical environment. The D F transition splitting, in the case of Eu(TTA) ?18C6, indicates more than 0 0 3 31 one site of symmetry occupied by Eu . | pt_BR |
