摘要

A top-emission inverted organic light-emitting diode (TEIOLED) was fabricated by using Al/AlN_x layer as the cathode in the device structure of glass/Al/AlN_x/AlQ_3/NPB/MTDATA/Au/Ag, where AlN_x ultra-thin layer was obtained from Al layer under 90 W microwave plasma treatments in Ar and N_2 mixed-gas environment. The N_2/Ar ratio and plasma treatment time were adjusted to obtain the maximum luminance and efficiency of 1206cd/m~2 and 0.51 cd/A, respectively, both at 17V. The AlN_x layer surface after plasma treatment was examined by atomic force microscope (AFM) to study the effects of surface roughness on the electroluminescent (EL) characteristics. The thickness of A1N_X layer also affected EL results apparently.
