· CdBr2

Cadmium bromide (CdBr₂) is an inorganic ceramic compound belonging to the cadmium halide family, characterized by ionic bonding between cadmium cations and bromide anions. While primarily studied in research contexts for semiconducting and photonic applications, CdBr₂ has attracted interest in optoelectronic device development, scintillation detectors, and radiation detection systems due to its potential for efficient photon conversion and tunable electronic properties.
