Line Plot from Scientific Research

Current density and b) luminance versus applied bias for NPB/Alq3organic light-emitting diodes based on a p-OA/Ag(12) anode (closed circles) or a glass/ITO anode with T= 83% and Rs = 20 sq−1. The corresponding external quantum efficiency versus luminance data are shown in (c). The structure of the p-OA/Ag(12) device is shown inset, with the ITO device having an identical structure except for the replacement of glass/OTS/p-OA/Ag(12) by glass/ITO.
