Figure 5: The performance of phosphorescent green OLEDs on SLG electrode.
From: Efficient and bright organic light-emitting diodes on single-layer graphene electrodes
(a) Pictures of flexible OLEDs on plastic substrate on SLG electrode. (b) The current density and luminance as a function of driving voltage. (c) EQE as a function of luminance for OLEDs on SLG electrode on flexible PET substrate, OLEDs on ITO on glass substrate and OLEDs using NPB hole transporting layer on SLG, (d) PE and CE of green OLEDs on SLG and ITO with enhanced coupling structure. The error bars represent the s.d. of multiple measurement results.
