Abstract

On the basis of the investigation into organic thin films preparations and device, the Organic Light-Emitting Device (OLED) with mutual doped transitional layer was designed and fabricated, mutual doped layer of N,N’-bis-(1-naphthyl)-N,N’-diphenyl-1, 1’-biphenyl-4,4’-diamine (NPB) and aluminum tri(8-hydroxyquinoline)(Alq₃) was used as emitting layer. Rate of NPB to Alq₃ was 10:1 at anode to 1:10 at cathode. Light-emitting performance of the OLED was analyzed. Compared with conventional device in which Alq₃ was used as emitting layer and blending device in which blending layer of NPB and Alq₃ was used as emitting layer, the device performance of mutual doped transitional layer was evidently improved because of the interface and the waveguide effect were eliminated effectively.
