aValues at a luminance of 1000 cd m−2.
bMaximum values.
cOperation time when the luminance decreases to 95% of its initial value at an initial luminance of 1000 cd m−2.
dOperation time when the luminance decreases to 95% of its initial value of device-driven under a constant current density of 5 mA cm−2. See Supplementary Fig. 5 for plots of the luminance and power efficiency as functions of current density.
