Two-dimensional lead halide perovskites represent a fascinating class of hybrid semiconductors for solar cell, light-emitting, nonlinear optical (NLO), and ferroelectric applications. A notable subset within this category is luminescent ferroelectrics, which have garnered considerable attention for their potential in integrated photoelectronic devices. In this study, we employed an organic amine halogenation strategy (also referred to as halogen engineering), which is renowned for its efficacy in inducing polar order through crystal engineering.

Lead halide perovskites have emerged as platforms for exciton-polaritonic studies at room temperature, thanks to their excellent photoluminescence efficiency and synthetic versatility. In this work, we find proof of strong exciton-photon coupling in cavities formed by the layered crystals themselves, a phenomenon known as the self-hybridization effect. We use multilayers of high-quality Ruddlesden-Popper perovskites in their 2D crystalline form, benefiting from their quantum-well excitonic resonances and the strong Fabry-Pérot cavity modes resulting from the total internal reflection at their smooth surfaces.

Here, we synthesized Co-based, anion-incorporated Ruddles-den-Popper perovskite electrocatalysts (LaSrCoO X ) and compared their catalytic performances in the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The ORR mechanism with the newly synthesized F-doped LaSrCoO catalyst was dominated by a four-electron process, and the number of electrons involved in the reaction increased compared with that for LaSrCoO. The OER activity of the hydride-doped LaSrCoO catalyst was the highest among the LaSrCoO system catalysts.

Structural characteristics on fluoride ion storage and conduction mechanism in LaSrMnO, and its fluoridated materials, LaSrMnOF and LaSrMnOF, for an all-solid-state fluoride ion battery positive electrode with a high volumetric capacity surpassing those of lithium-ion ones have been revealed using the Rietveld method and maximum entropy method. In LaSrMnO, once the F ions are taken into the NaCl slabs in its crystal through the charging process, it forms two stable fluoride compounds, LaSrMnOF and LaSrMnOF, with the help of the Mn oxidation reaction. In these oxyfluorides, thermal vibrations of the F ions inserted are much larger, especially in the - plane, than along the axis.
