White-Light Emission from Halide Perovskites Based on a Single Emissive Layer
Source abstract
Abstract
In contemporary society, lighting has become indispensable in both daily life and industrial activities. Researchers are actively developing new materials and technologies to meet global goals for clean, sustainable energy. Among them, halide perovskite materials play a vital role in light-emitting diodes (LEDs) due to their high carrier mobility, low exciton binding energy, and tunable emission wavelength. White perovskite light-emitting diodes (WPeLEDs) based on a single emission layer (SEL) feature simpler production processes and clearer luminescence mechanisms compared with other layered and series devices, attracting extensive research interest and showing great potential in practical applications. This Account systematically provides an overview of the recent advances in SEL-WPeLEDs. The concepts of perovskite materials and the luminescent principles of PeLEDs are first elaborated, and the typical approaches for perovskite film deposition are then summarized. Subsequently, the implementation strategies toward high-performance SEL-WPeLEDs of electric driving, including Perovskite with Self-trapped excitons, perovskite-organic molecule coupling, and metal ion doping, are carefully discussed. Finally, challenges and perspectives for the further development of SEL-PeLEDs are proposed.
