Monometallic and/or heterobimetallic Ln3+ (Ln = Eu, Gd, Tb, Dy) luminescent complex with thiophen-2-carboxylic acid was investigated. The ligand employed in this work, acts efficiently as antenna, absorbing and transfer energy to the emitter ion. The thiophen ring provides interesting features to the system, like higher polarizability due the sulphur atom. The complex were characterized by elemental analysis, complexometric titrimetry with edta, in order to quantify Ln3+, thermal analysis, FTIR and XRD which allowed propose two different stoichiometries [Ln(α-tpc)3(α-Htpc)2]n and [Ln(α-tpc)3(α-Htpc)] and the coordination of the ligand to the Ln3+ occurs through the bidentate coordination mode. By the UV-vis, photoluminescence and X rays spe...
