a Photoluminescence spectrum of the co-deposited film of 50 wt%-mCBP:SF3-TRZ, and electroluminescence spectrum of the device based on the undoped emission layer (only mCBP). b Magneto-electroluminescence profiles of the device based on the undoped emission layer with various emission wavelengths. c Schematic of energy transfer to TADF emitters in degraded devices. d Luminance decay curves of 4CzIPN-based OLEDs under constant high current of 30 mA cm−2. The pixels were fabricated on same substrate at the same time.
