The T50 lifetimes as a function of R0 for the control and target QLEDs. The dashed line fits the T50 data to the equation R0n T50  =  Constant, where n is the acceleration factor. a the control device. b the target device. c Summary of the reported red perovskite LED characteristics based on maximum EQE, T50 and roll-off. d–f EL performance of air-processed champion QLED. d Current density-voltage-radiance curve. e EQE curve. f EL spectra. g–i The storage stability of a typical air-processed QLED. g Current density-voltage curves of QLED after 0/1/2 weeks of storage. h Voltage-radiance curves of QLED after 0/1/2 weeks of storage. i EQE curves of QLED after 0/1/2 weeks of storage.
