a, The device lifetime of PeLED and hybrid tandem PeLED. The hybrid tandem PeLED showed device lifetime LT50 = 113 hours at L0 = 1,000 cd m−2 of electrical stress which corresponds to estimated lifetime of 5,596 hours at L0 = 100 cd m−2 using common acceleration factor of n = 1.78,30, whereas the single PeLED showed very short device lifetime (LT50 = 1 hour 48 min) at L0 = 100 cd m−2. b, EL spectra of hybrid tandem PeLED as a function of operating time at L0 = 1,000 cd m−2.
