Chemical compound

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 otherbromides, CsCdBr3 is non-hygroscopic,[2] giving it applications as an efficientupconversion material in solar cells.[3] As asingle crystal structure doped withrare-earth ions, it can be also used asactive laser medium. It is highly transparent in thevisible andinfrared regions and can be used as anonlinear optical crystal.[4]

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