Extrinsic nature of the broad photoluminescence in lead iodide-based ruddlesden⠍popper perovskites

HIGHLIGHTS

• who: Simon Kahmann from the InstitutUniversity of have published the research: Extrinsic nature of the broad photoluminescence in lead iodide-based Ruddlesdenu280dPopper perovskites, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
• what: In contrast to most reports, the authors focus on single crystals to exclude grain boundaries and interfaces as the origin of the BE. Through a combination of spectroscopic techniques, the authors show that intrinsic self-trapping is not responsible for the broad emission in these materials. In this light, the authors aim to spark a discussion on and a possible re-evaluation of previous . . .
