| 中文摘要 | we model the electrical behavior of organic light-emitting diodes whose emissive multilayer is formed by blends of an electron transporting material, tris-(8-hydroxyquinoline) aluminum (alq(3)) and a hole transporting material, n,n-'-diphenyl-n,n-'-bis(1,1(')-biphenyl)-4,4-diamine. the multilayer is composed of layers of different concentration. the alq(3) concentration gradually decreases from the cathode to the anode. we demonstrate that these graded devices have higher efficiency and operate at lower applied voltages than devices whose emissive layer is made of nominally homogeneous blends. our results show an important advantage of graded devices, namely, the low values of the recombination rate distribution near the cathode and the anode, so that electrode quenching is expected to be significantly suppressed in these devices. |
