Efficient Pure Blue Light-Emitting Diodes Based on CsPbBr3 Quantum-Confined Nanoplates

Wei Shen et al.

Summary: This study demonstrates the improvement of stability and efficiency in high-performance blue perovskite LEDs through four-aminobenzenesulfonic acid (SA) compensation and suitable MABr treatment. The coverage and thickness of the NPL layer were improved using an alternate droplet/spin coating method to prevent hole transport layer emission and increase the reproducibility of LED performance and spectra. Moreover, hole transport layers were designed to improve energy-level alignment.

Utilization of Trapped Optical Modes for White Perovskite Light-Emitting Diodes with Efficiency over 12%

Ziming Chen et al.

Summary: The main challenges in the metal-halide-perovskite light-emitting diode (PeLED) field are low light extraction efficiency (LEE) and difficulty in achieving white emission. A high-performance white PeLED with enhanced LEE was successfully constructed by coupling a blue PeLED with a red perovskite nanocrystal (PeNC) down-converter through a multilayer semitransparent electrode. This approach not only improved LEE by over 50%, but also achieved a high external quantum efficiency and luminance, representing state-of-the-art results in the field.

Menglong Liu et al.

Summary: Incorporating Mn2+ dopants into the perovskite lattice can significantly improve the stability of alpha-CsPbI3 and increase the photoluminescence quantum yield. Mn2+: CsPbI3 maintains high luminescence performance even after 45 days of exposure to air, in contrast to the rapid loss of luminescence in undoped CsPbI3. Additionally, introducing a LiF buffer layer can further enhance the device performance, particularly in terms of luminance and T-50 lifetime.
