金属卤化物钙钛矿纳米晶体具有高发射量子产率以及广泛的色彩可调性,已被广泛应用于发光二极管、高分辨率X射线成像以及光辐射传感器等光电子领域,但是量子效率不高和稳定性不佳的问题限制了钙钛矿基光电子器件的商业化发展.基于此,将钙钛矿纳米晶体嵌入金属有机框架(Metal-Organic Framework,MOF)中以稳定其发射属性,由此制备的钙钛矿-金属有机框架的复合结构(Perovskite Metal-Organic Framework,PeMOF)是高亮度的稳定发光体,使得多种有前景的光学应用成为可能.本文概述了PeMOF结构的制备及其在发光二极管中的最新进展和未来的研究重点.
The Research Progress of Metal-Organic Framework-Stabilized Perovskite Nanocrystal Light-Emitting Diodes
Metal halide perovskite nanocrystals exhibit high emission quantum yield and broad color tunability,making them widely used in optoelectronic fields such as light-emitting diodes (LEDs),high-resolution X-ray imaging and photo-radiation sensors. However,issues such as low quantum efficiency and poor stability have limited the commercialization of perovskite-based optoelectronic devices. To address these challenges,embedding perovskite nanocrystals into metal-organic frameworks ( MOFs ) has been proposed to stabilize their emission properties. The resulting perovskite-MOF composite structures ( PeMOF) are stable,high-brightness emitters,enabling a range of promising applications. This paper reviews the preparation of PeMOF structures and discusses the latest advancements and future research directions in their application to light-emitting diodes.
