Abstract

Bright, low-voltage driven colloidal quantum dot (QD)-based white light-emitting devices (LEDs) with practicable device performances are enabled by the direct exciton formation within quantum-dot active layers in a hybrid device structure. Detailed device characterization reveals that white-QLEDs can be rationalized as a parallel circuit, in which different QDs are connected through the same set of electrically common organic and inorganic charge transport layers.

摘要

在混合器件结构中，通过在量子点活性层内直接形成激子，实现了具有实际器件性能的明亮、低电压驱动的基于胶体量子点（QD）的白光发光器件（LED）。详细的器件特性研究表明，白光-QLED 可以被合理化为一个并联电路，其中不同的 QD 通过相同的一组电公共有机和无机电荷传输层连接。
