Caesium cadmium bromide (Cs Cd Br₃) is a synthetic crystalline material. It belongs to the AMX₃ group (where A = alkali metal, M = bivalent metal, X = halogen ion). Unlike most other bromides, CsCdBr₃ is non-hygroscopic,^[2] giving it applications as an efficient upconversion material in solar cells.^[3] As a single crystal structure doped with rare-earth ions, it can be also used as active laser medium. It is highly transparent in the visible and infrared regions and can be used as a nonlinear optical crystal.^[4]

Caesium cadmium bromide with the formula Cs₂CdBr₄ has also been synthesized.^[5]
