Overview
Terbium is a rare earth metal valued for its luminescent properties, particularly in green phosphors for displays and lighting.
Properties
It commonly forms +3 oxidation state compounds and contributes to magneto optical and luminescent materials.
Occurrence and Uses
Used in phosphors for fluorescent lamps and LEDs, magnet alloys and research in sensors and solid state devices.
Isotopes and Safety
Stable isotope Tb 159 is natural; terbium compounds are handled with standard industrial precautions and dust controls.
