Xyoo 1843, Karl G. Mosander ntawm Sweden nrhiav tau lub caijterbium los ntawm nws txoj kev tshawb fawb ntawm yttrium ntiaj teb. Daim ntawv thov ntawm terbium feem ntau cuam tshuam nrog kev siv tshuab thev naus laus zis, uas yog cov thev naus laus zis siv zog thiab kev paub txog kev ua haujlwm siab, nrog rau cov haujlwm uas muaj txiaj ntsig zoo rau kev lag luam, nrog rau kev nthuav dav txaus nyiam. Cov chaw thov tseem ceeb suav nrog cov hauv qab no.
(1) Phosphors yog siv los ua ntsuab hmoov activators nyob rau hauv peb thawj phosphors, xws li terbium activated phosphate matrix, terbium activated silicate matrix, thiab terbium activated cerium magnesium aluminate matrix, uas emit ntsuab teeb nyob rau hauv excitation.
(2) Magnetic optical cia cov ntaub ntawv, nyob rau hauv xyoo tas los no, terbium raws li magnetic optical cov ntaub ntawv tau mus txog ib tug loj-scale ntau lawm scale. Sib nqus optical discs tsim siv Tb-Fe amorphous nyias zaj duab xis raws li cov khoom siv hauv computer tau nce qhov peev xwm los ntawm 10-15 zaug.
(3) Magneto optical iav, Faraday rotatory iav uas muaj terbium, yog cov khoom siv tseem ceeb rau kev tsim cov rotators, cais tawm, thiab cov circulators dav siv hauv tshuab laser. Hauv particular, kev txhim kho thiab kev loj hlob ntawm terbium dysprosium ferromagnetostrictive alloy (TerFenol) tau qhib kev siv tshiab rau terbium. Terfenol yog ib yam khoom tshiab nrhiav tau nyob rau xyoo 1970s, nrog ib nrab ntawm cov hlau ua los ntawm terbium thiab dysprosium, qee zaum nrog ntxiv ntawm holmium, thiab tus so yog hlau. Cov hlau no yog thawj zaug tsim los ntawm Ames Laboratory hauv Iowa, Tebchaws Asmeskas. Thaum Terfenol muab tso rau hauv qhov chaw sib nqus, nws qhov loj me hloov pauv ntau dua li cov khoom sib nqus zoo tib yam, qhov kev hloov pauv no tuaj yeem ua rau qee qhov kev txav mus los ua tiav. Terbium dysprosium hlau yog thawj zaug siv nyob rau hauv sonar thiab tau dav siv nyob rau hauv ntau yam teb, xws li roj txhaj tshuab, kua valve tswj, micro positioning, mechanical actuators, mechanisms, thiab tis regulators rau aircraft thiab chaw telescopes.
