Fig. 8: Reliability and long-term stability of PeLEDs.

From: Proton-transfer-induced 3D/2D hybrid perovskites suppress ion migration and reduce luminance overshoot

Fig. 8

a J–V and b L–V curves of 3D PeLEDs with a repetition of voltage sweep and c, d those of 3D/2D hybrid PeLED. e Relative luminance of 3D/2D hybrid PeLED (green) and of 3D PeLED (red) over time. f Magnified version of relative luminance of PeLEDs showing an extremely reduced overshoot of luminance. g Voltage curves of 3D/2D hybrid PeLED (green) and 3D PeLED (red) over time under constant current to make PeLEDs have an emission of 100 cd m−2.
