Terbium is a chemical element with the symbol Tb and atomic number 65.

It is a silvery-white rare earth metal that is malleable and malleable.

Terbium is a very soft, silvery rare-earth metal mainly used in green phosphors. Along with divalent europium blue phosphors and trivalent europium red phosphors, terbium green phosphors are used to generate standard white light for indoor lighting. Terbium compounds are useful biological probes due to the long emission lifetime of terbium. As a component of Terfenol-D, terbium is also widely used in actuators, naval sonar systems, sensor Soundbug devices, and other magnetic devices. Terbium is also used as a crystal stabilizer in fuel cells operating at high temperatures.
