Abstract: ZnO-C60 and ZnO-MWCNT composite coating electrodes were fabricated by electrophoretic deposition on indium tin oxide(ITO) conductive glass surface, and the strength between coating and conductive glass was enhanced by heating treatment sequentially. The surface photography of electrode coatings was characterized by scanning electron microscopy(SEM), the optoelectronic properties were measured by CHI 705 electrochemical analyzer and PMI\|E electrochemiluminescence system. The results show that the ZnO-C60 composite coating electrode possesses a high stability and a strong photo-generated current over 30% compared with base current(where Δi=0.022 μA), the latter was studied by amperometric curve(i-t) and open circuit potential time(OCPT) under visible light irradiation. The ZnO-MWCNT composite coating electrode ownes a high stability and a strong electrochemiluminescent capability, the latter was investigated by cyclic voltammetry(CV) and amperometric curve  of electrochemiluminescence system. These two composite coating electrodes are hopeful of developing a brand optoelectronic and electrochemiluminescent electronic devices.
