摘要

Top-Emitting Quantum Dot Light-Emitting Diodes In article number 2206133, Jaehoon Kim, Kyung-Tae Kang, and co-workers present a novel light extraction structure for top-emitting quantum dot light-emitting diodes (QLEDs) called RaDiNa. By utilizing molded irregular holes on polydimethylsiloxane (PDMS) made by ZnO nanorods, the authors are able to widen the narrow viewing angle of top-emitting QLEDs, resulting in a remarkable 60% increase in external quantum efficiency.
