Popis: |
Spectral-luminescence characteristics of Yb3+ and Nd3+ ions in water solutions of their complexes with some organic dyes of sulfophenylphthalexones group have been considered. Complexes can be efficiently excited with visible light (λexc = 532 nm). 4f-Luminescence as a result of energy transfer from the dye moiety to the lanthanide ion was shown. Complexation of new polydentate ligand L of sulfophenylphthalexones type increases the luminescence lifetimes because of the reduced solvation of the ion by water. They were determined as 12.60 μs for complex Yb-L and 1.45 μs for Nd-L. |
