Kev ntxiv cov terbium oxide uas muaj kev huv siab rau cov ntawv thov no ua rau lub teeb ci ntsa iab thiab ua haujlwm tau zoo dua, ua rau nws yog qhov kev xaiv zoo rau cov tuam txhab tsim khoom.
Lwm daim ntawv thov tseem ceeb rau kev ntshiab siab 99.99% terbium oxide yog nyob rau hauv kev tsim cov iav kho qhov muag. Terbium cov khoom siv kho qhov muag tshwj xeeb ua rau nws yog ib qho khoom siv zoo heev rau cov qauv iav, tshwj xeeb tshaj yog thaum tsim cov iav tshwj xeeb thiab prisms. Cov khoom siv kho qhov muag no yog qhov tseem ceeb hauv ntau qhov chaw suav nrog kev sib txuas lus, kev kho mob duab, thiab kev tshawb fawb. Qhov ntshiab siab ntawm terbium oxide ua kom ntseeg tau tias cov iav kho qhov muag tau tsim nrog tsawg kawg nkaus impurities, ua rau muaj kev pom tseeb thiab kev ua tau zoo.
Ntxiv rau nws lub luag haujlwm hauv cov iav kho qhov muag, cov terbium oxide uas muaj cov khoom siv siab yog ib qho tseem ceeb ntawm cov khoom siv cia khoom magneto-optical. Cov khoom siv no siv cov nyhuv magneto-optical los nyeem thiab sau cov ntaub ntawv, ua rau lawv yog ib qho tseem ceeb hauv cov kev daws teeb meem khaws cov ntaub ntawv niaj hnub. Qhov muaj cov terbium oxide uas muaj cov khoom siv siab ua rau cov khoom siv sib nqus ntawm cov ntaub ntawv no zoo dua, yog li ua rau cov ntaub ntawv ceev thiab kev ua tau zoo dua. Raws li qhov kev thov rau kev khaws cov ntaub ntawv txuas ntxiv mus, qhov tseem ceeb ntawm cov terbium oxide uas muaj cov khoom siv siab hauv daim teb no tsis tuaj yeem hais ntau dhau.
Tsis tas li ntawd,siab purity 99.99% terbium oxideyog siv dav hauv kev tsim cov khoom siv sib nqus. Terbium cov khoom sib nqus tshwj xeeb ua rau nws zoo tagnrho rau kev tsim cov hlau nplaum ua haujlwm siab, uas yog qhov tseem ceeb hauv ntau yam kev siv, suav nrog cov cav hluav taws xob, cov tshuab hluav taws xob, thiab cov tshuab magnetic resonance imaging (MRI). Kev siv cov terbium oxide uas muaj cov khoom huv si hauv cov ntaub ntawv no ua kom lawv pom cov khoom sib nqus zoo tshaj plaws, yog li txhim kho kev ua haujlwm thiab kev ua tau zoo.
Lwm daim ntawv thov rau cov tshuaj terbium oxide uas muaj cov tshuaj ntshiab siab yog ua ib qho activator rau cov hmoov phosphor. Cov hmoov no siv rau ntau yam kev siv, suav nrog teeb pom kev zoo, cov zaub, thiab cov yam ntxwv kev ruaj ntseg. Kev ntxiv cov tshuaj terbium oxide uas muaj cov tshuaj ntshiab siab ua ib qho activator ua rau cov hmoov no ci ntsa iab dua, ua rau cov xim ci dua thiab ci dua. Daim ntawv thov no tseem ceeb heev thaum tsim cov zaub zoo thiab cov teeb pom kev zoo, qhov twg qhov tseeb ntawm xim thiab qhov ci ntsa iab yog qhov tseem ceeb.
Thaum kawg,terbium oxide uas muaj purity siabsiv tau ua ib yam khoom ntxiv rau cov ntaub ntawv garnet, uas siv rau ntau yam kev siv, suav nrog lasers thiab cov khoom siv kho qhov muag. Ntxiv terbium oxide rau cov qauv garnet tuaj yeem txhim kho lawv cov khoom siv kho qhov muag thiab sib nqus, ua rau lawv tsim nyog rau kev siv hauv cov ntawv thov thev naus laus zis siab heev.
Hauv kev xaus,siab purity 99.99% terbium oxideyog ib qho tshuaj sib xyaw ua ke uas siv tau ntau yam lag luam. Nws lub luag haujlwm hauv kev tsim cov hlau terbium, iav kho qhov muag, magneto-optical cia, cov ntaub ntawv sib nqus, phosphor activators thiab garnet additives qhia txog nws qhov tseem ceeb hauv kev siv tshuab niaj hnub. Thaum kev lag luam txuas ntxiv hloov zuj zus thiab kev thov rau cov ntaub ntawv ua tau zoo dua txuas ntxiv mus, qhov tseem ceeb ntawm cov purity siab terbium oxide yuav txuas ntxiv loj hlob, paving txoj hauv kev rau cov kev daws teeb meem tshiab thiab kev nce qib hauv ntau qhov chaw.
