In this review, the recent development of blue perovskite light-emitting diodes (PeLED) are summarized. On deep-blue (≤465 nm) perovskite nanomaterials of different structural forms are mainly focused, including nanocrystals (NCs), quantum dots (QDs), nanoplatelets (NPLs), quasi-2D thin film, 3D bulk thin film, as well as lead-free perovskite nanomaterials. The current challenges are also examined in producing efficient deep-blue PeLED, such as material and spectral instability, imbalance charge transport, Joule heat impact, and poor optoelectronic performance. Several strategies are further discussed to overcome these challenges and achieve efficient deep-blue PeLED for next-generation display technology.
在本综述中，总结了蓝色钙钛矿发光二极管（PeLED）的最新进展。主要聚焦于不同结构形式的深蓝色（≤465 nm）钙钛矿纳米材料，包括纳米晶体（NCs）、量子点（QDs）、纳米片（NPLs）、准二维薄膜、三维块状薄膜以及无铅钙钛矿纳米材料。还研究了在生产高效深蓝色PeLED时当前面临的挑战，如材料和光谱不稳定性、电荷传输不平衡、焦耳热影响以及光电性能不佳等。进一步讨论了几种策略，以克服这些挑战并实现用于下一代显示技术的高效深蓝色PeLED。
