High‐Brightness and Ultra‐Long‐Lifetime Spin Quantum Dot Light‐Emitting Diodes Enabled by Efficient Injection of Spin‐Polarized Holes Through a Hybrid Hole Transport Layer

Advanced Science, EarlyView.
This work employs a hybrid hole transport layer to enhance hole transport efficiency, resulting in improved performance for the final device. It achieves an external quantum efficiency of 6.68%, a circularly polarized electroluminescence asymmetry factor of 0.026, and a high luminance of 14,370 cd/cm2, representing the highest luminance reported to ...
