Xyoo 1886, tus txiv neej Fabkis txoj Boise Baudelaire tau ua tiav holmium rau hauv ob lub ntsiab lus, ib qho tseem hu ua holmium, thiab lwm lub npe hu ua dysrosium raws li lub ntsiab lus ntawm "nyuaj tau" los ntawm holmium (Figures 4-11).Dysprosium tam sim no ua lub luag haujlwm tseem ceeb hauv ntau lub teb chaws high-tech. Cov kev siv tseem ceeb ntawm dysprosium yog raws li hauv qab no.
(1) Raws li ib qho ntxiv rau neodymium hlau boron cov hlau nplaum ruaj khov, ntxiv 2% rau 3% dysprosium tuaj yeem txhim kho nws txoj kev coercivity. Yav dhau los, qhov kev thov rau dysprosium tsis siab, tab sis nrog kev xav tau ntau ntxiv rau neodymium hlau boron hlau nplaum, nws tau dhau los ua cov khoom tsim nyog ntxiv, nrog rau qib ntawm 95% mus rau 99.9%, thiab qhov kev thov tseem nce sai.
(2) Dysprosium yog siv los ua tus activator rau phosphors, thiab trivalent Dysprosium yog ib qho kev cog lus ua kom muaj zog ion rau ib qho chaw emission tricolor luminescent cov ntaub ntawv. Nws yog tsim los ntawm ob pawg emissions, ib qho yog daj emission, thiab lwm yam yog xiav emission. Dysprosium doped luminescent cov ntaub ntawv tuaj yeem siv ua tricolor phosphors.
(3) Dysprosium yog cov khoom siv hlau tsim nyog rau kev npaj cov hlau loj magnetostrictive Terfenol, uas tuaj yeem ua kom cov neeg kho tshuab ua kom tiav.
(4) Dysprosium hlau tuaj yeem siv los ua cov khoom siv kho qhov muag magneto nrog kev ceev ceev thiab kev nyeem ntawv.
(5) Rau kev npaj dysprosium teeb, cov khoom siv ua haujlwm siv hauv dysprosium teeb yog dysprosium iodide. Hom teeb no muaj qhov zoo xws li lub teeb ci siab, xim zoo, xim kub, me me, thiab ruaj khov arc. Nws tau siv los ua lub teeb pom kev zoo rau cov yeeb yaj kiab, luam ntawv, thiab lwm yam kev siv teeb pom kev zoo.
(6) Dysprosium yog siv los ntsuas neutron spectrum los yog neutron absorber nyob rau hauv atomic zog kev lag luam vim nws loj neutron capture cross section.
(7) DysAlsO12 kuj tseem siv tau los ua cov khoom sib nqus ua haujlwm rau cov tub yees sib nqus. Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, daim ntawv thov kev lag luam ntawm dysprosium yuav txuas ntxiv nthuav dav thiab txuas ntxiv.
