| 中文摘要 | in this paper, we study the effects of electrical annealing at different voltages on the performance of organic light-emitting diodes. the light-emitting diodes studied here are single-layer devices based on a conjugated dendrimer doped with 2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole as the emissive layer. we find that these devices can be annealed electrically by applying a voltage. this process reduces the turn-on voltage and enhances the brightness and efficiency. we obtained an external electroluminescence quantum efficiency of 0.07% photon/electron and a brightness of 2900 cd m(-2) after 12.4 v electrical annealing, which are about 6 times and 9 times higher than un-annealing devices, respectively. the improved luminance and efficiency are attributed to the presence of a space charge field near the electrodes caused by charging of traps. |
