Abstract

The excitation and fluorescence spectra of PEOx EuBr3 (x=8, 16, 20, 24, 32) and PPO32 EuBr3 were recorded and analyzed in terms of the barycenters of each level of the ground septet of Eu3+. The site symmetry of the Europium ion is tentatively assigned to the C1,2, C5 or C2v cases. The maximum fluorescence intensity for each composition, together with the measured values for the lifetimes, suggest the possibility of these two polymeric electrolytes being used as fluorescent materials.
