Caesium cadmium bromide

Caesium cadmium bromide (CsCdBr3) 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]
