a, EQE versus current density. b, Radiant exitance versus current density. The maximum optical power densities are 28.5 W cm−2 and 25.1 W cm−2 for the standard bottom-emission and microcavity top-emission PeLEDs, respectively. The active area of the devices is 0.02 mm2. Pulse duration: 1 μs, repetition rate: 100 Hz.
