喷墨打印镉基量子点发光二极管(QLEDs)有望应用于大尺寸全彩显示面板且具有材料利用率高的特点而广受关注。但目前喷墨打印器件效率远低于旋涂制备的同结构器件，针对这一问题，本文研究了在PVK空穴传输层上喷墨打印绿光量子点器件及量子点墨水溶剂对传输层界面的影响。研究发现，喷墨打印过程中的层间互溶是影响器件效率的关键，在采用正交溶剂结合喷墨工艺优化实现了高质量的膜层与界面后，获得了6.3%的喷墨印刷绿光QLEDs外量子效率。

Inkjet-printed quantum dot light-emitting diodes(QLEDs) have received widely attention, owing to their potential for use in large-area full-color pixelated display with high material utilization. However, the performance of the inkjet-printed QLEDs is always inferior to the spin coated devices with the same structure. In this study, the performance of the inkjet-printed green QLEDs based on PVK layer and the effects of quantum dot ink formula on transport layer interfaces were investigated. It is revealed that layer erosion is a key issue for performance of inkjet-printed QLEDs. An external quantum efficiency of 6.3% was achieved in inkjet-printed green QLEDs with high-quality film and interface by employing the orthogonal solvent via optimizing inkjet printing technology.
