All‐Solution‐Processed Perovskite Light‐Emitting Transistors Enabled by a Fully Organic Architecture
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 ...
