Abstract

We observed EL properties based on poly(3,6-N-2-ethylhexyl carbazolyl cyanoterephthalidene) (PECCP) and PECCP/Alq₃ emitting material devices with doped PPy conducting layer (>5 S/cm) on top of rough ITO (surface resistance: less than 7 Ω/□). The ITO/PECCP/Alq₃/Al device shows relatively high luminance efficiency, (0.17 lm/W), because of the PECCP layer. The PPy conducting layer is working on improving I-V characteristics of PECCP/Alq₃ small molecule EML and PECCP EML system on ITO which has a rough surface of more than 1000 angstroms peak to peak level. In the PECCP EML device, when PPy is layered on top of ITO, the turn-on voltage is lowered from 15 to 9 V.
