Abstract
Multilayer polymer-organic light emitting diodes (P-OLEDs) were assembled with different transparent conductive oxide (TCO) and aluminum as the anode and cathode, respectively. Two types of TCOs, ITO (indium tin oxide) or FTO (fluorine tin oxide), with different sheet resistances, from 10 to 61 Ω/□, were used. A blend of poly[(1,4-phenylene)-alt-2,7(9,9 dioctylfluorene)] and an europium complex (20 %) was used as the polymeric photoactive layer of the devices. The performance of P-OLEDs showed that those having the FTO film with the lowest sheet resistance presented the lowest threshold voltage, while those having the ITO with the lowest sheet resistance presented the highest luminance among all types of devices obtained.
