recommendations! Published in 2025 at "Advanced Optical Materials"

DOI: 10.1002/adom.202502072

Abstract: Vacuum‐deposited perovskite light‐emitting diodes (PeLEDs) have demonstrated great potential for next‐generation light sources. However, vacuum‐deposited perovskites suffer from high defect densities due to the lack of sufficient passivation strategies. Herein, an effective in situ passivation… read more here.
