Abstract
Characteristics of electrochemically-driven light-emitting devices M/M EH-PPV+TBATS/ITO (where M=Al, Cu, Au and TBATS=tetrabutylammonium p-to luenesulfonate) are reported. Light emission is observed in forward an d reverse bias modes in each device. Characteristics of ''3-layer'', ' '4-layer'' and ''5-layer'' light-emitting devices having the configura tions, Al/MEH-PPV/ITO, Al/MEH-PPV/EB/ITO and Al/EB/MEH-PPV/EB/ITO have been studied. Light emission is observed in forward bias only for the first device but in forward and reverse bias modes for the latter two devices. Operation in AC mode is also observed. Photovoltages are obs erved for all these devices in the range 0.15-0.87 v when irradiated w ith Ar+ laser or overhead projector lamp.
