Terbium, is a chemical element with the symbol Tb and atomic number 65. It is a silvery-white rare earth metal that is malleableductile and very hard. It 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.
