In this study, a new lanthanide terbium complex, Tb(pzda)3(NO3)3·nH2O, was synthesized by a hydrothermal method and characterized by Fourier transform infrared spectroscopy (FT-IR) and energy-dispersive X-ray spectroscopy (EDS). It was found that the as-synthesized Tb-complex exhibited good electrochemiluminescence (ECL) behavior in the presence of triethanolamine (TEOA) in a HAc-NaAc buffer solution on a glassy carbon electrode. The possible reaction mechanism has been discussed based on the fluorescence spectra and ECL spectra.

The quenching behavior can be observed with a 100-fold excess of bergenin over Ru(bpy)3(2+). In the presence of 0.

The quenching behaviors can be observed with a 100-fold excess of SDS over Ru(bpy)(3)(2+). The mechanism of quenching is believed to involve energy transfer from the excited-state Ru(bpy)(3)(2+*) to the dimer of SDS, which was formed after the electrochemical oxidation of SDS at the electrode surface.
