Kushandisa Rare Earth Oxides Kugadzira Fluorescent Magirazi
Zvishandiso zveRare Earth Elements Maindasitiri akadzikwa, akadai sezvemagetsi, kugadzira magirazi, magetsi, uye simbi, ave achishandisa zvinhu zvisingawanzoitiki kwenguva refu.Maindasitiri akadai, kana asanganiswa, anoverengera 59% yehuwandu hwepasi rose.Ikozvino nzvimbo nyowani, dzakakura, dzakadai semabhatiri alloys, ceramics, uye magineti echigarire, ari kushandisawo zvisingawanzo zvinhu zvepasi, izvo zvinomiririra imwe 41%. Rare Earth Elements muGlasi Kugadzirwa Mumunda wekugadzira magirazi, zvisingawanzo pasi oxides zvakadzidza kwenguva refu.Kunyanya zvakanyanya, maitiro egirazi anogona kuchinja nekuwedzera kweaya makomisheni.Mumwe musayendisiti weGermany anonzi Drossbach akatanga basa iri muma1800s paakaita patent uye akagadzira musanganiswa weasingawanzo pasi oxides kuti decolorizing girazi. Kunyangwe muchimiro chisina kuchena nemamwe maokisi epasi asingawanzo, iyi yaive yekutanga kushandiswa kwekutengesa kwecerium.Cerium yakaratidzwa kuva yakanakisa kunyura ultraviolet pasina kupa ruvara muna 1912 naCrookes weEngland.Izvi zvinoita kuti zvive zvakakosha kune ekudzivirira magirazi emaziso. Erbium, ytterbium, uye neodymium ndiwo maREE anoshandiswa zvakanyanya mugirazi.Optical communication inoshandisa erbium-doped silica fiber zvakanyanya;engineering zvinhu kugadzirisa inoshandisa ytterbium-doped silica fiber, uye girazi lasers inoshandiswa kune inertial kuvharirwa fusion inoshandisa neodymium-doped.Iko kugona kushandura fluorescent zvimiro zvegirazi ndeimwe yeakanyanya kukosha kushandiswa kweREO mugirazi. Fluorescent Properties kubva kuRare Earth Oxides Yakasarudzika nenzira yekuti inogona kuratidzika seyakajairwa pasi pechiedza chinooneka uye inogona kuburitsa mavara akajeka kana ichifadzwa nemamwe mafunguro, girazi refluorescent rine akawanda maapplication kubva kukurapa kwekufungidzira uye kutsvagisa kwebiomedical, kuyedza midhiya, kutsvaga uye art yegirazi enamels. Iyo fluorescence inogona kuramba ichishandisa REOs yakanyatso kuisirwa mugirazi matrix panguva yekunyunguduka.Zvimwe girazi zvinhu zvine chete fluorescent coating zvinowanzokundikana. Munguva yekugadzira, kuiswa kweiyo isingawanzo pasi ion muchimiro inoguma neoptical glass fluorescence.Maerekitironi eREE anosimudzwa kunzvimbo yekunakidzwa apo simba rinouya rinoshandiswa kufadza aya maion anoshanda zvakananga.Kubuda kwechiedza kwehurefu hwewavelength uye simba rakaderera kunodzosera mamiriro ekunakidzwa kumamiriro epasi. Mumaindasitiri maitiro, izvi zvinonyanya kubatsira sezvo zvichibvumira inorganic girazi microspheres kuti iiswe mubatch kuti ione mugadziri uye nhamba yejeti yemhando dzakawanda dzechigadzirwa. Kutakurwa kwechigadzirwa hakukanganiswe neiyo microspheres, asi rumwe ruvara rwechiedza runogadzirwa kana ultraviolet mwenje inopenya pabatch, iyo inobvumira kuti chaiyo yechinhu chizivikanwe.Izvi zvinogoneka nemhando dzese dzezvinhu, kusanganisira hupfu, mapurasitiki, mapepa, uye zvinwiwa. Mhando yakakura kwazvo inopihwa mumamicrospheres nekuchinja huwandu hwema paramita, senge chaiyo reshiyo yeakasiyana REO, particle size, particle size distribution, chemical composition, fluorescent properties, color, magnetic properties, uye radioactivity. Izvo zvinobatsirawo kugadzira fluorescent microspheres kubva mugirazi sezvo inogona kudonhedzwa kune akasiyana madhigirii neREO's, inoshingirira tembiricha yakanyanya, kushushikana kwakanyanya, uye inert kemikari.Mukuenzanisa nemapolymers, iwo ari epamusoro munzvimbo dzese idzi, izvo zvinovatendera kuti vashandiswe mune yakaderera zvakanyanya muzvigadzirwa. Iyo yakaderera solubility yeREO musilica girazi chimwe chinogona kudzikisira sezvo izvi zvinogona kutungamira mukuumbwa kwemasumbu epasi asingawanzo, kunyanya kana iyo doping concentration yakakura kupfuura equilibrium solubility, uye inoda chiito chakakosha kudzvanyirira kuumbwa kwemasumbu.
