Sky-Blue Phosphorescent OLEDs with 34.1% External Quantum Efficiency Using a Low Refractive Index Electron Transporting Layer

Blue‐phosphorescent organic light‐emitting diodes (OLEDs) with 34.1% external quantum efficiency (EQE) and 79.6 lm W−1 are demonstrated using a hole‐transporting layer and electron‐transporting layer with low refractive index values. Using optical simulations, it is predicted that outcoupling effici...
