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.
