This tutorial review highlights recent work on white organic light-emitting diodes (WOLEDs) in view of their potential as the next generation lighting source. It begins with an introduction to the fundamentals of WOLEDs, and then discusses the key factors that determine the performance of WOLEDs. The focus is on charges and excitons, which are the fundamental elements associated with the physical processes within the device. Correspondingly, the third section illustrates how to control the efficiency and color quality of WOLEDs through the management of charges and excitons. Finally, challenges and opportunities for the further improvement of device performance will be discussed.
本教程综述重点介绍了白色有机发光二极管(WOLED)的最新研究进展,因为它们有望成为下一代照明光源。本文首先介绍了 WOLED 的基本原理,然后讨论了决定 WOLED 性能的关键因素。重点是电荷和激子,它们是与器件内物理过程相关的基本元素。相应地,第三部分说明了如何通过管理电荷和激子来控制 WOLED 的效率和颜色质量。最后,讨论了进一步提高器件性能的挑战和机遇。
