Published in 2021 at "Inorganic chemistry"

DOI: 10.1021/acs.inorgchem.1c01277

Abstract: In lead(II) halide compounds including virtually all lead halide perovskites, the Pb2+ 6s lone pair results in distorted octahedra, in accordance with the pseudo-Jahn-Teller effect, rather than generating hemihedral coordination polyhedra. Here, in contrast, we… read more here.

Published in 2024 at "Inorganic chemistry"

DOI: 10.1021/acs.inorgchem.4c04423

Abstract: Metal halide luminescent materials, particularly those doped with ns2 ions, exhibit exceptional optical properties. However, the luminescent mechanisms associated with the stereochemical activity of lone-pair electrons remain insufficiently explored. In this study, zero-dimensional (0D) tin-based… read more here.
