摘要：
An organic light-emitting diode (OLED) with a liquid host of 9-(2-ethylhexyl)carbazole (EHCz) doped with a guest dye of 5, 6, 11, 12-tetraphenylnapthacene ( rubrene) was demonstrated. Here the poly (3, 4-ethylenedioxy thiophene) : poly (styrenesulphonate)(PEDOT : PSS) and Cs2CO3 were served as the hole injection material and electron injection material, respectively. The device structure consists of ITO/PEDOT : PSS/EH Cz : rubrene/Cs2CO3/ITO. Electroluminescence from rubrene with the highest external quantum efficiency of 0.03% at 0.26 mA center dot cm(-2) was obtained. The photoluminescence (PL) and PL quantum efficiency of the materials were further studied.
