In article number 1906742, Majid Pahlevani, Yujun Shi, and co‐workers present a new quantum‐dot light‐emitting diode device architecture, integrating multiple poly(methylmethacrylate) (PMMA) electron blocking layers between a pair of red‐emitting QD layers. The experimental optimization and numerical simulation demonstrate significant improvement in brightness and current efficiency from the structure consisting of two PMMA and three QD layers due to the reduction in electron leakage by the addition of PMMA layers.

发光二极管:通过插入多个聚(甲基丙烯酸甲酯)作为电子阻挡层的高效量子点发光二极管(Adv。Funct。Mater。50/2019)

在1906742号文章中,Majid Pahlevani,Yujun Shi和他的同事们提出了一种新的量子点发光二极管器件架构,该结构在一对红色发光的QD层之间集成了多个聚甲基丙烯酸甲酯(PMMA)电子阻挡层。实验优化和数值模拟表明,由于添加了PMMA层而减少了电子泄漏,因此由两个PMMA层和三个QD层组成的结构显着提高了亮度和电流效率。
