摘要

钙钛矿发光二极管（PeLED）由于其>20%的外量子效率（EQE）而引起了相当大的研究关注，并且具有进一步改进的潜力。然而，与红色和绿色PELED相比，蓝色PELED尚未得到广泛研究，这限制了其在亮度和全色显示器领域的商业应用。在这篇综述中，蓝色PeLED的相关研究按钙钛矿的组成进行了分类。概述了钙钛矿薄膜的主要挑战和相应的优化策略。接下来，从传输层和界面层的角度综述了蓝色PELED器件结构设计的新策略。因此，对蓝色PeLED的未来发展方向进行了讨论。这篇综述可以为优化蓝色PELED的钙钛矿膜和器件结构，从而扩大其开发和应用范围提供指导。

Review of blue perovskite light emitting diodes with optimization strategies for perovskite film and device structure

Perovskite light emitting diodes (PeLEDs) have attracted considerable research attention because of their external quantum efficiency (EQE) of >20% and have potential scope for further improvement. However, compared to red and green PeLEDs, blue PeLEDs have not been extensively investigated, which limits their commercial applications in the fields of luminance and full-color displays. In this review, blue-PeLED-related research is categorized by the composition of perovskite. The main challenges and corresponding optimization strategies for perovskite films are summarized. Next, the novel strategies for the design of device structures of blue PeLEDs are reviewed from the perspective of transport layers and interfacial layers. Accordingly, future directions for blue PeLEDs are discussed. This review can be a guideline for optimizing perovskite film and device structure of blue PeLEDs, thereby enhancing their development and application scope.
