Recent Progress in High‐Efficiency Blue Perovskite Light‐Emitting Diodes
Source abstract
Abstract
Abstract Halide perovskite materials are novel display materials owing to their excellent optical and electrical properties. In recent years, the performance of perovskite light‐emitting diodes (PeLEDs) has improved significantly, with the external quantum efficiency (EQE) approaching 30% for green and red PeLEDs. In sharp contrast, the development of blue PeLEDs lags far behind that of their counterparts in terms of efficiency and stability. This review focuses on recent advancements and the key factors affecting the performance of blue PeLEDs. The component tailoring strategies are meticulously summarized first. Subsequently, the detailed methods to improve the performance of blue PeLEDs with various wavelengths are elucidated. The remaining challenges, including efficiency, stability, and lead toxicity, are discussed. Finally, the fabrication techniques for further applications of blue PeLEDs are delineated.
