Surface-binding molecular multipods strengthen the halide perovskite lattice and boost luminescence

Kim et al. report a strategy to reduce the dynamic disorder of the perovskite lattice by using CMMs that adsorb on the surface of PeNCs via van der Waals interactions and hydrogen bonding. The resulting pure green LEDs satisfying the Rec. 2020 color standard show a high EQE of 26.1%.

Characterization of stability and challenges to improve lifetime in perovskite LEDs

Low stability of perovskite light-emitting diodes (PeLEDs) is the biggest obstacle to the commercialization of PeLED displays. Here, we cover the current status and challenges in analysing and improving the stability of PeLEDs and suggest some advice that will benefit the community to boost the operational lifetime of PeLEDs.
