green perovskite light-emitting diodes, efficiency; stability
This work reviews the research history of green perovskite light-emitting diodes (GPeLEDs), introduces perovskites of different dimensions, and discusses the common synthesis methods of perovskites. Additionally, strategies to improve the stability and luminous efficiency of GPeLEDs are summarized, including component engineering, phase engineering, ligand engineering, additive engineering, interface engineering, and optical coupling structure strategy. Finally, the development state of GPeLEDs is summarized and future prospects are discussed.
Perovskite, as a star fluorescent material, has the characteristics of adjustable luminescence peak, high color purity, high photoluminescence quantum yield, and low cost, showing significant potential in the photoelectric field. Among the RGB colors for display devices, green is the most sensitive color for human eyes, and green perovskite light-emitting diodes (GPeLEDs) have aroused much interest in recent years. In this work, the research history of GPeLEDs is reviewed, the perovskites of different dimensions are introduced, and the common synthesis methods of perovskites are discussed. Besides, the strategies to improve the stability and luminous efficiency of GPeLEDs are summarized, including component engineering, phase engineering, ligand engineering, additive engineering, interface engineering, and optical coupling structure strategy. Finally, the development state of GPeLEDs is summarized and prospected. This work is expected to stimulate more unprecedented achievements derived from GPeLEDs, thus promoting their practical applications in future ultra-high-definition displays. This work summarizes the state-of-the-art research progress of green perovskite light-emitting diodes (GPeLEDs), and strategies to improve the stability and luminous efficiency of GPeLEDs are introduced, including component engineering, phase engineering, ligand engineering, additive engineering, interface engineering, and optical coupling structure strategy. Challenges and perspectives for achieving high-performance GPeLEDs are also proposed.image
