· Ca3AsBr3

Ca₃AsBr₃ is a halide perovskite ceramic compound containing calcium, arsenic, and bromine in a mixed-anion structure, representing an emerging class of inorganic materials studied primarily in academic and research settings rather than established commercial production. This material family is being investigated for potential applications in optoelectronic devices, solid-state lighting, and radiation detection due to the tunable electronic properties characteristic of halide perovskites, though Ca₃AsBr₃ specifically remains largely in the exploratory phase with limited industrial adoption compared to more established perovskite variants.
