Perovskite light-emitting diodes (PeLEDs) have attracted tremendous attention due to their superior properties and astonishing progress. However, the commercial applications of PeLEDs are impeded by their inferior operational stability. The successful introduction of novel functional materials is a promising strategy towards achieving efficient and stable PeLEDs. Low-dimensional nanomaterials (LDNMs) with unique electrical, mechanical and surface properties have been extensively studied as a kind of multi-functional material in PeLEDs. Here, the review surveys the current status of PeLEDs and emphasizes the incorporation of LDNMs in PeLEDs. Three key aspects including charge-transport modulation, emitting layer optimization and electrode engineering for enhancing the efficiency and stability of PeLEDs by LDNMs are discussed. In the end, the challenges that hinder the application of LDNMs in PeLEDs are outlined. Some enlightening insights are discussed to tackle the challenges and advance this encouraging research field closer to industrial applications.
