| Details | An extended displacement current measurement (DCM) is performed to analyze the operation mechanisms of a poly(p-phenylenevinylene) derivative (Super Yellow)-based light-emitting electrochemical cell (LEC). The characteristics of the actual current, displacement current, and electroluminescence (EL) intensity during the relaxation processes of electrochemical doping are simultaneously measured. The extended DCM enables us to comprehensively analyze the operation mechanisms of LECs on the basis of the simultaneous observations of electrical and luminous characteristics, including their transient changes. |
