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.
