Terbium (Tb) Fun Facts
"The Green-Screen, the hero who brings the vibrant green to energy-efficient lights and TV screens."
The true essence of Terbium (Tb) on the molecular frontier.
Terbium is a silvery-white, malleable, rare earth metal.
Terbium is found in the green phosphor in a low-energy fluorescent light bulb.
Terbium is a key part of Terfenol-D, an alloy that changes shape in magnetic fields � used in sonar systems.

Did You Know?
It is a key component in producing the green phosphor used in trichromatic lighting, such as fluorescent lamps and modern TV and smartphone screens.
The alloy Terfenol-D, made with terbium, dysprosium, and iron, expands or contracts when exposed to a magnetic field (a property called magnetostriction) and is used in advanced sonar systems and sensors.
Like its neighbors yttrium, erbium, and ytterbium, it is named after the village of Ytterby in Sweden.
It is a silvery-white metal that is soft enough to be cut with a knife.
It is used as a dopant in solid-state devices and as a crystal stabilizer in fuel cells that operate at high temperatures.
