Cathodic Electrochemiluminescence from Rhodamine B in Aqueous Media Using Peroxydisulfate as Co-reactant

In this study, peroxydisulfate (S2O82−) was used as a co-reactant for the first time to generate a highly stable cathodic electrochemiluminescence (ECL) of rhodamine B (RhB) on a glassy carbon electrode. The ECL emission spectrum is almost identical to its photoluminescence spectrum and the intensity is significantly enhanced in the presence of nonionic surfactant TritonX-100.
