· JVASP-32759· BiBr

Bismuth bromide (BiBr) is an inorganic ceramic compound composed of bismuth and bromine, belonging to the halide ceramic family. It is primarily of research and developmental interest rather than a mature engineering material, with potential applications in optoelectronic and photonic devices due to bismuth's strong spin-orbit coupling effects. BiBr and related bismuth halides are being investigated for next-generation semiconductor applications, including perovskite solar cells, X-ray detectors, and scintillation materials, where bismuth's high atomic number and halide compositions offer advantages in radiation interaction and charge transport.
