摘要

金属卤化物钙钛矿（MHPs）具有光电子特性，在发光应用中具有很高的优势。与多晶（PC）钙钛矿相比，单晶（SC）钙钛矿表现出高载流子迁移率，减少离子迁移和抑制俄歇复合。然而，SC钙钛矿发光二极管（SC- peleds）面临以下挑战：1)高纵横比SC薄膜的生长；ii) SC发光层与载流子输运层之间的界面接触。本文首先介绍了MHP SC薄膜的生长方法。然后，总结了近年来sc - pled的研究进展，并对优化器件性能的策略进行了综述。最后，对进一步提高sc - ped的性能和实际应用提出了展望。

Metal Halide Perovskite Single-Crystal Thin Films: From Films Growth to Light-Emitting Application

Metal halide perovskites (MHPs) show optoelectronic properties that are highly advantageous for light-emitting applications. Compared to polycrystalline (PC) perovskite, single-crystal (SC) perovskite exhibits high carrier mobility, reducing ion migration and suppressing Auger recombination. However, SC perovskite light-emitting diodes (SC-PeLEDs) face the following challenges: i) the growth of high-aspect-ratio SC films; ii) the interfacial contact between the SC light-emitting layers and the carrier transport layers. This review begins with the growth methods of MHP SC thin films. Then, the recent research progress of SC-PeLEDs is summarized, and the strategies for optimizing device performance are also reviewed. Finally, perspectives are proposed further to enhance the performance and practical application of SC-PeLEDs.
