Manipulation of the Structure and Optoelectronic Properties through Bromine Inclusion in a Layered Lead Bromide Perovskite.

ABSTRACT: One of the great advantages of organic-inorganic metal halides is that their structures and properties are highly tuneable and this is important when optimizing materials for photovoltaics or other optoelectronic devices. One of the most common and effective ways of tuning the electronic structure is through anion substitution. Here, we report the inclusion of bromine into the layered perovskite [H₃N(CH₂)₆NH₃]PbBr₄ to form [H₃N(CH₂)₆NH₃]PbBr₄·Br₂, which contains molecular bromine (Br₂) intercalated between the layers of corner-sharing PbBr₆ octahedra.
