Terbium Oxide

Terbium, atomic no. 65, symbol Tb, weight at 158.93, is primarily used in phosphors, particularly in fluorescent lamps and as the high intensity green emitter used in projection televisions, such as the yttrium-aluminum-garnet (Tb:YAG) variety.
Terbium responds efficiently to x-ray excitation and is, therefore, used as an x-ray phosphor.
Terbium alloys are also used in magneto-optic recording films, such as TbFeCo.
