The incorporation of dETL facilitated the increased exciton recombination resulting in a 133% improvement in efficiency and a 300% increase in device lifetime (LT95). Moreover, degradation in the emitting layer was diminished by changing the degradation zone to the dETL, as confirmed by laser desorption/ionization-time of flight (LDI-TOF) analysis.
