- We performed optical simulations and experiments to investigate the internal optics of graphene anode organic light-emitting diodes (OLEDs). The efficiencies, emission distribution, and spectral characteristics of four-layered graphene anode OLEDs were extracted and compared to those of ITO anode OLEDs. Unlike the case of the ITO anode OLED, the efficiencies and emission distributions of graphene anode OLEDs showed a weak dependency on the thickness of the organic layers. Furthermore, marginal changes in the emission spectra were observed. These results were ascribed to the negligible presence of a microcavity effect in the graphene anode OLED.
