Metal halide perovskite nanocrystals are recent emerging light emitters with high emission quantum yields and wide color tunability from the ultraviolet to near infrared regions. Perovskite nanocrystals have been applied in high-performance optoelectronics such as bright light-emitting diodes, high-resolution X-ray imaging and photo/radiation sensors, and have received wide attention in this field. However, key challenges such as the poor material stability in the ambient environment and the short operational lifetime under external stress such as an electrical field or illumination still hinder the further development of perovskite nanocrystal-based optoelectronics. Recent intriguing works have smartly incorporated perovskite nanocrystals in metal–organic framework (MOF) matrices to stabilize their emission properties. The resulting perovskite–MOF structures are bright light emitters that have enabled a variety of promising applications. This perspective provides an overview of the recent progress in perovskite/MOF heterostructures and their applications in photonic devices. It first introduces the challenges of stabilizing perovskite nanocrystals, and then discusses how perovskite/MOF structures overcome these problems. We then go over the development of photonic devices using perovskite/MOF as light emitters and describe their potential uses in clean energy conversion and sensing applications.

钙钛矿纳米晶体稳定在用于发光器件的金属有机框架中

金属卤化物钙钛矿纳米晶体是最近出现的发光体，具有高发射量子产率和从紫外到近红外区域的宽颜色可调性。钙钛矿纳米晶体已在高亮发光二极管、高分辨率X射线成像和光/辐射传感器等高性能光电子学中得到应用，在该领域受到广泛关注。然而，诸如周围环境中材料稳定性差以及在电场或照明等外部应力下使用寿命短等关键挑战仍然阻碍了钙钛矿纳米晶体基光电子学的进一步发展。最近有趣的工作巧妙地将钙钛矿纳米晶体掺入金属-有机框架 (MOF) 基质中，以稳定其发射特性。由此产生的钙钛矿-MOF结构是明亮的发光体，已经实现了各种有前途的应用。该观点概述了钙钛矿/MOF异质结构的最新进展及其在光子器件中的应用。它首先介绍了稳定钙钛矿纳米晶体的挑战，然后讨论了钙钛矿/MOF结构如何克服这些问题。然后，我们回顾了使用钙钛矿/MOF 作为光发射器的光子器件的开发，并描述了它们在清洁能源转换和传感应用中的潜在用途。它首先介绍了稳定钙钛矿纳米晶体的挑战，然后讨论了钙钛矿/MOF结构如何克服这些问题。然后，我们回顾了使用钙钛矿/MOF 作为光发射器的光子器件的开发，并描述了它们在清洁能源转换和传感应用中的潜在用途。它首先介绍了稳定钙钛矿纳米晶体的挑战，然后讨论了钙钛矿/MOF结构如何克服这些问题。然后，我们回顾了使用钙钛矿/MOF 作为光发射器的光子器件的开发，并描述了它们在清洁能源转换和传感应用中的潜在用途。
