ceramic

· JVASP-28430· CdIBr

CdIBr is a mixed halide ceramic compound combining cadmium, iodine, and bromine, belonging to the family of cadmium halide materials. This material is primarily investigated in research contexts for optoelectronic and radiation detection applications, where its wide bandgap and halide crystal structure offer potential advantages in photon sensitivity and scintillation performance. CdIBr is notable within the cadmium halide family as an intermediate composition between pure iodide and bromide variants, potentially offering tuned electronic properties compared to single-halide alternatives, though it remains an emerging material with limited commercial deployment.
