Abstract: All‐inorganic bismuth‐halide perovskites are promising alternatives for lead halide perovskites due to their admirable chemical stability and optoelectronic properties; however, these materials deliver inferior photoluminescence (PL) properties, severely hindering their prospects in lighting applications.

Abstract: Perovskite-phase cesium bismuth halide (Cs3Bi2X9; X = Cl, Br, I) nanocrystals were synthesized using a hot-injection approach. These nanocrystals adopted ordered-vacancy perovskite crystal structures and demonstrated composition-tunable optical properties. Growth occurred by initial formation of… read more here.

DOI: 10.1039/c9tc06313g
Abstract: Metal halide hybrid perovskites containing high atomic number (Z) elements have a large absorption cross-section for high-energy X-rays, and emerge as excellent semiconductors for direct X-ray detection. Here we report a new bismuth-based perovskite derivative… read more here.
