Mu 1886, Mfalansa Boise Baudelaire bwinobwino analekanitsa holmium mu zinthu ziwiri, wina akadali kudziwika monga holmium, ndipo wina dzina lake dysrosium zochokera tanthauzo la "zovuta kupeza" kuchokera holmium (Figures 4-11).Dysprosium pakali pano ikugwira ntchito yofunika kwambiri m'magawo ambiri apamwamba kwambiri. Ntchito zazikulu za dysprosium ndi izi.
(1) Monga chowonjezera cha neodymium iron boron maginito okhazikika, kuwonjezera 2% mpaka 3% dysprosium kumatha kusintha mphamvu yake. M'mbuyomu, kufunikira kwa dysprosium sikunali kwakukulu, koma ndi kuchuluka kwa maginito a neodymium iron boron, kunakhala chinthu chofunikira chowonjezera, chokhala ndi kalasi ya 95% mpaka 99,9%, ndipo kufunikira kukukulirakuliranso.
(2) Dysprosium imagwiritsidwa ntchito ngati activator ya phosphors, ndipo trivalent Dysprosium ndi ion yodalirika yoyambitsa ma ion a single emission center tricolor luminescent luminescent. Amapangidwa makamaka ndi magulu awiri a emission, imodzi ndi yellow emission, ndipo ina ndi blue emission. Dysprosium doped luminescent zida zitha kugwiritsidwa ntchito ngati tricolor phosphors.
(3) Dysprosium ndi zofunika zitsulo zopangira pokonzekera lalikulu magnetostrictive aloyi Terfenol, amene angathe kupangitsa mayendedwe enieni makina kuti akwaniritse.
(4) Chitsulo cha Dysprosium chitha kugwiritsidwa ntchito ngati chosungira maginito-optical yokhala ndi liwiro lojambulira komanso chidwi chowerenga.
(5) Pokonzekera nyali za dysprosium, chinthu chogwiritsidwa ntchito mu nyali za dysprosium ndi dysprosium iodide. Nyali yamtunduwu ili ndi ubwino monga kuwala kwakukulu, mtundu wabwino, kutentha kwamtundu wapamwamba, kukula kochepa, ndi arc yokhazikika. Zakhala zikugwiritsidwa ntchito ngati gwero lowunikira mafilimu, kusindikiza, ndi ntchito zina zowunikira.
(6) Dysprosium imagwiritsidwa ntchito kuyeza mawonekedwe a nyutroni kapena ngati chotengera nyutroni m'makampani opanga mphamvu za atomiki chifukwa cha gawo lalikulu la nyutroni yolanda.
(7) DysAlsO12 Angagwiritsidwenso ntchito ngati maginito ntchito zinthu maginito refrigeration. Ndi chitukuko cha sayansi ndi ukadaulo, magawo ogwiritsira ntchito dysprosium apitiliza kukula ndikukula.
