Effects of Nitridation Time on Top-emission Inverted Organic Light Emitting Diode
A top-emission inverted organic light-emitting diode (TEIOLED) was fabricated by using Al/AlNx layer as the cathode in the device structure of glass/Al/AlNx/AlQ3/NPB/ MTDATA/Au/Ag, where AlNx ultra thin layer was obtained from Al layer under 90Wmicrowave plasma treatments in Ar and N2 mixed gas environment. The N2/Ar ratio and plasma treatment time were adjusted to obtain the maximum luminance and efficiency of 1206 cd/m2 and 0.51 cd/A, respectively, both at 17 volts. The AlNx layer surface after plasma treatment was examined by atomic force microscope to study the effects of surface roughness on the effectroluminescent (EL) characteristics. The AlNx layer thickness also affected the EL results apparently.
