Abstract

Abstract : Monitoring emission and potentials at both the working and counter electrodes provides new insight into a proposed cathodic electrochemiluminescence system. Abstract : A new approach to examine electrochemiluminescence (ECL), in which the potentials at both the working and counter electrodes are measured and the emitted light is detected by a photomultiplier tube, camera and then a charge-coupled device (CCD) spectrometer, provides unequivocal evidence that the purported cathodic ECL of [Ru(bpy)3 ] 2+ and tri- n -propylamine actually arises from anodic reactions at the counter electrode.
