Electrochemical synthesis of Tb3+ waterless luminescent complex compounds with some fluorine-containing aromatic carboxylic acids

Abstract

Electrochemical synthesis of terbium (III) waterless complex compounds with fluorine-containing aromatic carboxylic acids of TbL3 content was performed. The structure of obtained complex compounds coordination site was studied using the IR-spectroscopy method, and it was found out, that the coordination between used ligands and Tb3+ ions is bidentate. We also studied luminescent properties of the obtained compounds and showed that the terbium (III) with pentafluorobenzoic acid complex compound has the highest luminescent efficiency.
