Abstract

Abstract: The fluorescence lifetimes of nine complexes of Eu3+ with β-diketone-L₄EuQH have been studied by laser induced spectrofluorometer. Results show that the fluorescence lifetimes of L₄EuQH with a given Q, measured at the peaks of 6130 Å, 5910 Å and 5797 Å, are the same, on the other hand, the influence of Q on the fluorescence lifetimes of L₄EuQH may be caused by H-bond.

Key words: fluorescence lifetimes, laser, spectrographic analysis, rare earth, europium complexes
