Device architecture and energy level diagram. (a) Architecture of the OLEDs is ITO/2T-NATA (20 nm)/NPB (30 nm)/emitting layer (20 nm)/TPBi (30 nm)/LiF (0.3 nm)/Al (150 nm), and the doping concentrations of the emitting layer (EML) of BN:DSB:DCJTB are 100:3:0.21 for device A and 100:20:4 for device B. (b) Device energy level diagram.
