a, b, Distributions of maximum EQE (a) and maximum brightness (b) obtained from 90 QD-LEDs with double EML. c, Operational lifetimes of QD-LEDs with a double EML consisting of C/S/S-Cl(l) over C/S/S-Cl(f) for different initial brightness values. d, Measured lifetime (T50) of the devices versus brightness. The T50 value at 100 cd m−2 was estimated by fitting with the empirical equation \({L}_{0}^{n}\times {T}_{50}={\rm{constant}}\), where L0 is the initial brightness and n is the acceleration factor.
