Electroluminescence from bipolar resonant tunneling diodes
, 1992 The incorporation of an AlAs/GaAs resonant tunneling structure inside a GaAs p-n junction leads to strong quantum-well electroluminescence originating from electron and hole tunneling into the resonant tunneling structure. A large peak-to-valley ratio of

Donor Extended Blue TADF Dendrimer for High‐Performance Solution‐Processed OLEDs
Advanced Science, EarlyView.A dendronized MR‐TADF emitter, DOBNA‐SpAc‐DCz, was designed to improve solubility, hole transport, and exciton dynamics for solution‐processed OLEDs. Incorporation of ter(tert‐butylcarbazole) dendrons decreases ΔEST and accelerates RISC, yielding short delayed lifetimes (∼2 µs).

Advanced Electronic Materials, EarlyView.A novel strategy for achieving high current density in van der Waals (vdW) heterostructure‐based light‐emitting devices (LEDs) is proposed. Based on this concept, an LED utilizing a WS2/WSe2 heterostructure was fabricated, achieving a current density of 9.4 × 104 A/cm2.

All‐Solution‐Processed Perovskite Light‐Emitting Transistors Enabled by a Fully Organic Architecture
Advanced Electronic Materials, EarlyView.Fully solution‐processed light‐emitting transistors based on CsPbBr3 perovskite nanocrystals (Pe‐LETs) are demonstrated using an all‐organic platform. By optimizing film formation and device integration, the Pe‐LETs achieve bright green emission with excellent color purity and a peak external quantum efficiency of 4.17 × 10−3 %, marking a step forward ...

Electroluminescence from single crystal Cu2O diodes
, 1979 We have measured the infrared electroluminescence in different types of single crystal Cu2O–Cu diodes under forward bias at various temperatures. Diodes which showed double-injection current-voltage characteristics in previous studies showed transient ...
