Terbium
Rare earth metal used in green phosphors and magnetostrictive alloys.
Last updated
Its terbium(III) cation is brilliantly fluorescent, producing a bright lemon-yellow color.[1] Below 219 K, terbium exhibits simple ferromagnetic ordering; between 219 K and 230 K it is in a helical antiferromagnetic state, and above 230 K it becomes a disordered paramagnet.[2]

Key facts and history
Spectral analysis by Marc Delafontaine allowed identification of the separate elements, but the names erbium and terbium were switched and have remained so.[3] No mineral has been discovered that is dominated by terbium.[4]
What the research sources say
The Stanford Advanced Materials account states that terbium's luminescent prowess has become instrumental in shaping modern electronic screens.[5] Terbium's magnetic properties position it as a key player in emerging technologies like quantum computing and magnetic storage.[5] The Holden history report notes that the name derives from the village of Ytterby in Sweden, where the mineral ytterbite was first found.[6] According to the CRC Handbook, terbium serves as a dopant in calcium fluoride, calcium tungstate, and strontium molybdate for use in solid-state devices.[7]
