Perovskite materials, celebrated for their exceptional optoelectronic properties, have seen extensive application in the field of light-emitting diodes (LEDs), where research is as abundant as the proverbial "carloads of books." In this review, the research of perovskite materials is delved into from a dimensional perspective, with a focus on the exemplary performance of low-dimensional perovskite materials in LEDs. This discussion predominantly revolves around perovskite quantum wires and perovskite nanorods. Perovskite quantum wires are versatile in their growth, compatible with both solution-based and vapor-phase growth, and can be deposited over large areas-even on spherical substrates-to achieve commendable electroluminescence (EL). Perovskite nanorods, on the other hand, boast a suite of superior characteristics, such as polarization properties and tunability of the transition dipole moment, endowing them with the great potential to enhance light extraction efficiency. Furthermore, zero-dimensional (0D) perovskite materials like nanocrystals (NCs) are also the subject of widespread research and application. This review reflects on and synthesizes the unique qualities of the aforementioned materials while exploring their vital roles in the development of high-efficiency perovskite LEDs (PeLEDs).
钙钛矿材料因其卓越的光电性能而备受赞誉，在发光二极管（LED）领域有着广泛应用，相关研究多得如 proverbial “carloads of books”（字面意思：一车车的书，可意译为“海量”）。在本综述中，从维度角度深入探讨了钙钛矿材料的研究，重点关注低维钙钛矿材料在LED中的优异性能。此讨论主要围绕钙钛矿量子线和钙钛矿纳米棒展开。钙钛矿量子线生长方式多样，与基于溶液和气相生长均兼容，并且可以大面积沉积——甚至在球形衬底上——以实现可观的电致发光（EL）。另一方面，钙钛矿纳米棒具有一系列优异特性，如极化特性和跃迁偶极矩的可调性，这赋予它们极大潜力来提高光提取效率。此外，像纳米晶体（NCs）这样的零维（0D）钙钛矿材料也是广泛研究和应用的对象。本综述在探索上述材料在高效钙钛矿发光二极管（PeLEDs）发展中的关键作用时，对它们的独特性质进行了思考和总结。
