Pb4SBr6

Pb₄SBr₆ is a mixed halide-chalcogenide ceramic compound belonging to the family of lead-based inorganic solids, combining lead, sulfur, and bromine in its crystal structure. This material is primarily of research interest for optoelectronic and solid-state applications, where lead halides and chalcogenides have shown promise for photovoltaic devices, scintillators, and radiation detection due to their electronic band structure and high atomic mass. While not yet established in mainstream industrial production, compounds in this family are being investigated as alternatives to cadmium-based semiconductors and as potential materials for next-generation X-ray and gamma-ray detectors where high stopping power and carrier mobility are advantageous.
