Abstract

Abstract: Two ternary complexes Eu(TTA)₃L and Eu(BTA)₃L(where TTA=thenoyltri-fluoroacetone, BTA=benzoyltrifluoroacetone, L=4,5-diazafluorene-9-one)have been synthesized and characterized by elemental analysis, IR, UV and fluorescence spectrum analyses. The results showed that in methyl cyanide the complexes gave a higher fluorescence intensity.

Key words: europium, β-diketone, diazafluoreneone, ternary complex, synthesis, fluorescence spectrum
