Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>In this paper, we present highly efficient inverted phosphorescence organic light‐emitting diodes (PhOLEDs) based on ultrathin emitting layers (EML). By introducing 1.5 nm EML with co‐host, the inverted PhOLED exhibits external quantum efficiency (EQE) of 31.1%. Besides, a multilayer mCP/MoO₃/Al/Cs₂CO₃ works well as charge generation unit (CGU) for tandem inverted PhOLED with 0.5 nm EML.</p> </abstract>
