EMISSÃO QUASE BRANCA DE UM COMPLEXO BINUCLEAR DE DISPRÓSIO(III) CONTENDO DICARBOXILATOS

Abstract

This work reports the synthesis and characterization of the novel [Dy2(dcpz)2(suc)(H2O)8](H2O)1.5 (dcpz = 3,5-dicarboxypyrazolate, suc = succinate). The structure should probably consist of a binuclear species in which Dy3+ ions are linked by two different bridging organic ligands. Luminescent studies were carried out and revealed that the Dy3+complex exhibits a near white emission under UV excitation.
