Perovskite materials have emerged as a promising class of optoelectronic materials due to their exceptional properties, including high photovoltaic efficiencies and potential applications in light-emitting diodes (LEDs), lasers, and light-emitting transistors. This review discusses the rapid advancements in perovskite-based light-emitting devices, highlighting their performance, challenges, and future prospects. Perovskite materials, with their high photoluminescence quantum yields (PLQY) and efficient charge transport, have achieved remarkable results in light-emitting devices, such as LEDs with external quantum efficiencies (EQE) of 8% and current efficiencies of 43 Cd A⁻¹. These achievements have surpassed those of organic LEDs (OLEDs) in terms of brightness and efficiency within a short period. The key factors contributing to the success of perovskite light-emitting devices include their low defect densities, direct bandgap, and tunable optical properties. Perovskite materials can be categorized into 3D, lower-dimensionality layered, and nanostructured forms. Each of these forms offers unique advantages for light-emitting applications. For instance, 3D perovskites exhibit high photoluminescence quantum yields and efficient charge transport, while lower-dimensionality layered perovskites offer enhanced optical properties due to quantum confinement effects. Nanostructured perovskites, such as nanoparticles, nanoplates, and nanowires, provide additional flexibility in tuning optical and electronic properties. The review also addresses the challenges in perovskite light-emitting devices, including operational stability, material synthesis, and device fabrication. It discusses the potential of perovskites in laser applications, where their low threshold for amplified spontaneous emission and tunable bandgaps make them suitable for a wide range of applications. The review concludes with an outlook on the future of perovskite light-emitting devices, emphasizing the need for further research to improve device performance, stability, and scalability. Overall, perovskite materials are showing great promise as versatile materials for light-emitting applications, with the potential to revolutionize optoelectronic technology.Perovskite materials have emerged as a promising class of optoelectronic materials due to their exceptional properties, including high photovoltaic efficiencies and potential applications in light-emitting diodes (LEDs), lasers, and light-emitting transistors.
