Table 1 Summary of EQEs and lifetimes (LT70).

The EQEs are obtained at 100 cd/m2, and the lifetime values are obtained at 1000 cd/m2. RT refers to the tool’s standard temperature, which is close to 30°C. The 0.85 Tg criteria refer to the temperature closest to the optimal growth condition of the TPBi layers.
