Caesium cadmium bromide explained

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,[1] giving it applications as an efficient upconversion material in solar cells.[2] 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.[3]

Caesium cadmium bromide with the formula Cs2CdBr4 has also been synthesized.[4]
