Broadband light emitting zero-dimensional antimony and bismuth-based hybrid halides with diverse structures

A series of hybrid metal halides were obtained, and among them, (TMEDA) 3 Sb 2 Br 12 ·H 2 O exhibits the strongest yellow emission centered at 625 nm with a full-width at half-maximum of ∼150 nm originating from self-trapped excitons.
