调控空穴传输层的分子取向提高量子点发光二极管稳定性策略

Strategies for Regulating the Molecular Orientation of the Hole Transport Layer to Improve the Stability of Quantum Dot Light-emitting Diodes

量子点发光二极管是当前研究的重要方向,QLED因其良好的性能受到了广泛的关注,而其寿命与效率也成为了当前制约其发展的问题。QLED的稳定性主要取决于载流子注入稳定性和电荷平衡。通过调控空穴传输层的分子取向的方式调节载流子与电荷平衡,一定程度上提升了QLED的稳定性。

Quantum dot light-emitting diode is an important direction of current research, QLED has received extensive attention because of its good performance, and its life and efficiency have become the current problems restricting its development. The stability of QLED depends mainly on carrier injection stability and charge balance. The carrier and charge balance are adjusted by regulating the molecular orientation of the hole transport layer, which improves the stability of QLED to a certain extent.
