Abstract

In this work, the luminescence properties of three europium complexes with ligands based on 2,2’–bipyridyldicarboxylic acid with various counterions (TFA, NO₃, Cl) were studied in the form of powders and acetonitrile solutions. Their luminescence spectra were recorded at room temperature and in liquid nitrogen. We obtained and calculated the following luminescence characteristics: luminescence lifetime, relative intensities of each luminescence peak, asymmetry coefficient, radiative lifetime, internal quantum yield, luminescence quantum yield, and the effectiveness of sensitization.
