Abstract: Electrochemically induced luminescence (ECL) is an attractive analytical technique, which could be used for many applications. Introduction of reactants and/or removal of formed products both are very important issues in the most ECL-based systems. The introduction/removal of chemicals could be achieved by flow-through cells. Flow-through cells are not efficient in all designs of ECL systems. Therefore, rotating disk electrode (RDE) could be a valuable alternative, which could increase the efficiency of ECL-based devices. In this work, the RDE was used for the evaluation of electroluminescence of tris(2,2′-bipiridin)dichlorruthenium(II)hexahydrate ([Ru(bpy)₃]²⁺), 5-Amino-2,3-dihydro-1,4-phthalazinedione (luminol), and N-(4-aminobuthyl)-N-ethyl-isoluminol (ABEI). Detection limits, optimal pH and potential values, and emission spectra were determined for each compound.
