摘要：

Blue perovskite light-emitting diodes (PeLEDs) restrict the rapid development of full-color display and white lighting technology of perovskite. Quasi-two-dimensional (Q2D) perovskite enables to realize blue light emission via strict control on layer number and use of quantum confinement effect and can significantly improve the stability of perovskite film and PeLEDs by using hydrophobic organic ligands, which has gradually become a research hotspot in the field of perovskites. This review summarizes the research progress on Q2D blue PeLEDs from three aspects of component engineering, film process and device optimization, and analyzes the challenges faced by Q2D blue PeLEDs and the efficiency improvement approaches. At last, this paper envisages the future research direction and feasible solutions.
