Isticmaalka Oksaydhyada Dhulka Naadirka ah si aad u Samayso Muraayadaha Fluorescent
Xigasho:AZoMCodsiyada Walxaha Dunida Naadirka ahWarshadaha la aasaasay, sida kicinta, muraayadaha, iftiiminta, iyo biraha, ayaa isticmaalayay walxo dhif ah oo dhulka ah muddo dheer. Warshadaha noocaan ah, marka la isku daro, waxay xisaabiyaan 59% wadarta isticmaalka adduunka oo dhan. Hadda kuwa cusub, meelaha kobaca sare leh, sida alloys batteriga, ceramics, iyo magnets joogto ah, ayaa sidoo kale samaynaya isticmaalka curiyeyaasha dhulka naadir, taas oo ka dhigan 41% kale.Walxaha Dunida Naadirka ah ee Soo saarista DhalaaradaDhinaca wax-soo-saarka dhalada, oksaydhyada dhulka dhifka ah ayaa muddo dheer la darsay. Si gaar ah, sida sifooyinka muraayadda ay u bedeli karaan marka lagu daro xeryahooda. Saynisyahan Jarmal ah oo la odhan jiray Drossbach ayaa shaqadan bilaabay sannadihii 1800-aadkii markii uu shati-raadiyey oo soo saaray isku-dar ah oksaydhyo dhuleed naadir ah oo loogu talagalay midabaynta dhalada.Inkasta oo qaab cayriin ah oo leh oksaydhyada dhulka naadirka ah, tani waxay ahayd ganacsigii ugu horreeyay ee cerium. Cerium waxaa la tusay in uu aad ugu fiican yahay nuugista ultraviolet iyada oo aan midab la siinin 1912 Crookes of England. Tani waxay faa'iido badan u leedahay muraayadaha indhaha ee ilaaliya.Erbium, ytterbium, iyo neodymium ayaa ah kuwa ugu badan ee REE-yada loo isticmaalo galaaska. Isgaadhsiinta indhaha waxay si aad ah u isticmaashaa erbium-doped silica fiber; Habaynta agabka injineernimada waxay isticmaashaa ytterbium-doped silica fiber, iyo laysarka dhalooyinka ee loo isticmaalo isku-xidhka xidhidhnimada inertial waxay adeegsadaan neodymium-doped. Awoodda lagu beddelayo sifooyinka florescent ee muraayadda waa mid ka mid ah isticmaalka ugu muhiimsan ee REO ee muraayadda.Alaabta Fluorescent ee ka timid Oxide Earth ee Naadirka ahU gaar ah sida ay ugu muuqan karto mid caadi ah oo hoos yimaada iftiinka muuqda oo soo saari kara midabyo muuqda marka ay ku faraxsan yihiin hirarka hirarka qaarkood, galaaska fluorescent ayaa leh codsiyo badan oo ka yimid sawir-qaadista caafimaadka iyo cilmi-baarista biomedical, si loo tijaabiyo warbaahinta, raadinta iyo dhaldhalaalka farshaxanka.Fluorescence-ku wuu sii jiri karaa iyadoo la isticmaalayo REO-yada si toos ah loogu dhex daray matrixka galaaska inta lagu jiro dhalaalidda. Alaabta kale ee dhalada ah ee leh dahaarka fluorescent kaliya ayaa badanaa ku guuldareysta.Inta lagu jiro wax-soo-saarka, soo-bandhigidda ions dhulku naadirka ah ee qaab-dhismeedku waxay keenaan fluorescence muraayadda indhaha. Elektaroonada REE-da waxa loo kiciyaa xaalad xamaasad leh marka isha tamarta soo socota loo isticmaalo in si toos ah loo kiciyo ion firfircoon. Sii daynta iftiinka ee hirarka dhererka dheer iyo tamarta hoose waxay ku soo celisaa xaaladdii xiisaha lahayd ee dhulka.Nidaamyada warshadaha, tani waxay si gaar ah faa'iido u leedahay maadaama ay u oggolaanayso microspheres galaas ah inorganic in la geliyo dufcaddii si loo aqoonsado soo saaraha iyo tirada badan ee noocyo badan oo alaab ah.Gaadiidka badeecada ma saameeyaan microspheres, laakiin midab gaar ah oo iftiin ah ayaa la soo saaraa marka iftiinka ultraviolet lagu iftiimiyo dufcadda, taas oo u oggolaanaysa caddaynta saxda ah ee walxaha si loo go'aamiyo. Tani waxay suurtogal u tahay dhammaan noocyada agabka, oo ay ku jiraan budada, balaastikada, waraaqaha, iyo dareeraha.Kala duwanaansho aad u weyn ayaa lagu bixiyaa microspheres iyadoo la beddelayo tirada cabbirrada, sida saamiga saxda ah ee REO kala duwan, cabbirka walxaha, qaybinta cabbirka walxaha, halabuurka kiimikada, guryaha fluorescent, midabka, guryaha magnetic, iyo shucaaca.Waxa kale oo ay faa'iido u leedahay in laga soo saaro microspheres fluorescent galaaska sababtoo ah waxaa lagu dhejin karaa heerar kala duwan oo REO ah, oo u adkeysan kara heerkulka sare, cadaadis sare, iyo kimikal ahaan aan firfircooneyn. Marka la barbardhigo polymers, waxay ka sarreeyaan dhammaan meelahaas, taas oo u oggolaanaysa in loo isticmaalo qadar aad u hooseeya ee alaabta.Solubility yara hooseeya ee REO ee galaaska silica waa hal xaddidaad oo suurtagal ah maxaa yeelay tani waxay horseedi kartaa samaynta kooxo naadir ah oo dhulka ah, gaar ahaan haddii xoogga la saaro doping-ku uu ka weyn yahay milanka dheellitirka, wuxuuna u baahan yahay tallaabo gaar ah si loo xakameeyo samaynta kooxaha.
