Hoob laug, lub sijhawm 68 hauv lub rooj noj mov.
Qhov nrhiav pom ntawmhoob laugyog tag nrho ntawm cov twists thiab lem. Xyoo 1787, hauv lub nroog me ntawm utter, 1.6 kilometers ntawm Stockholm, Sweden, lub ntiaj teb tshiab tau pom nyob rau hauv lub ntiaj teb dub, muaj npe YTTRIUMIUMIEL raws li qhov chaw nyob ntawm kev tshawb pom. Tom qab cov kev tawm tsam Fabkis, Chemist Mossander siv cov thev naus laus zis tshiab los txo qis theem pibyttriumlos ntawm yttrium ntiaj teb. Txij ntawm no, tib neeg tau pom tias YTTRIUM lub ntiaj teb tsis yog "ib qho tivthaiv" thiab pom ob lwm tus oxides: lub paj yeeb yog hu uaErbium oxide, thiab lub teeb liab doog ib qho yog hu ua terbium oxide. Xyoo 1843, Mossander nrhiav tau erbium thiabterbium, tab sis nws tsis ntseeg tias ob yam yeeb yam pom tau dawb huv thiab tej zaum xyaw nrog lwm yam khoom. Nyob rau hauv qab xyoo hauv qab no, cov neeg tau pom tias muaj tseeb ntau cov ntsiab lus sib xyaw ua ke hauv nws, thiab maj mam pom lwm yam LANThanide hlau cov ntsiab lus ntxiv rau ntawm erbium thiab terbium.
Txoj kev tshawb fawb ntawm cov khoom tawg tsis yog du li nws nrhiav pom. Txawm hais tias Maussand nrhiav pom cov paj yeeb erbium oxide hauv 1843, nws tsis yog kom txog xyoo 1934 uas cov qauv ntshiab ntawmErbium Hlautau muab rho tawm vim muaj kev txhim kho txuas ntxiv hauv txoj kev lim. Los ntawm cua sov thiab ua kom huverbium chlorideThiab cov poov tshuaj, tib neeg tau ua tiav qhov txo qis ntawm cov khoom tawg ntawm cov hlau potassium. Txawm yog li ntawd, cov khoom ntawm pawg neeg ntawm cov khoom siv tau zoo ib yam li lwm yam kev tshawb fawb hlau, ua rau muaj ze li ntawm 50 xyoo ntawm kev tshawb fawb, xws li Magnetism, kev sib txhuam lub zog, thiab ua kom muaj zog. Txog rau xyoo 195, nrog daim ntawv thov ntawm tus qauv tshwj xeeb ntawm cov khoom siv hluav taws xob ntawm cov khoom siv kho qhov muag, erbium tau txais kev saib xyuas thiab ntau daim ntawv thov ntawm cov khoom siv.
Erbium, nyiaj dawb, muaj cov khoom pov thawj kev ntxhib los mos thiab tsuas yog cov khoom pov thawj muaj zog ferromagnetism ze ze li cas. Nws yog lub superconductor thiab maj mam oxidized los ntawm huab cua thiab dej ntawm chav tsev kub.Erbium oxideYog cov xim liab liab feem ntau siv hauv kev lag luam porcelain thiab yog ci zoo. Erbium yog muaj cov pob zeb volcanic thiab muaj cov ntxhib pob zeb loj nyob rau yav qab teb.
Erbium muaj cov khoom tsim kho tau zoo thiab tuaj yeem hloov infrared rau hauv pom kev, ua rau nws cov khoom zoo tshaj plaws rau kev ua cov khoom siv tsis pom thiab ua lub zeem muag hmo ntuj. Nws tseem yog ib qho kev txawj ntse hauv photon nrhiav kom tau, muaj peev xwm ntawm cov qib tsis tu ncua hauv cov khoom siv kom paub ntxiv hauv cov photon kom tsim lub photon ntes. Txawm li cas los xij, kev ua tau zoo ntawm kev nqus tau ncaj qha ntawm cov photons los ntawm kev sib tw ions tsis yog siab. Nws tsis yog kom txog xyoo 1966 uas cov kws tshawb fawb tau tsim tsa cov nyom ntawm cov cim hluav taws xob los ntawm kev ntsuas Optau thiab tom qab ntawd hloov lub zog los ua erbium.
Lub hauv paus ntsiab lus ntawm Erbium laser zoo ib yam li ntawd ntawm Holmium laser, tab sis nws lub zog loj dua li ntawm Holmium laser. Ib lub pob zeb laser nrog nthwv dej ntawm 2940 nanometers tuaj yeem siv los txiav cov nqaij mos. Txawm hais tias hom laser no nyob hauv nruab nrab infrared cheeb tsam muaj kev nkag siab tsis zoo los ntawm noo noo hauv tib neeg cov nqaij mos, ua tiav cov txiaj ntsig zoo nrog tsawg dua. Nws tuaj yeem ua kom zoo, zom, thiab tshem cov ntaub so ntswg mos, ua tiav cov qhov txhab zoo kom zoo. Nws yog dav siv hauv Laser phais, dawb cataract, kev zoo nkauj, thiab kev tshem tawm wrinkle.
Xyoo 1985, University of Southampton hauv tebchaws Askiv thiab NorthEintern University hauv Nyij Pooj ua tau zoo tshaj plaws cov khoom siv hluav taws xob. Tam sim no, Wuhan Optics Valley nyob rau Wuhan, Tuam Tshoj muaj peev xwm ua tau cov khoom siv hluav taws xob no ua rau cov khoom siv hluav taws xob no thiab xa tawm rau North America, Europe, thiab lwm qhov chaw. Daim ntawv thov no yog ib qho kev tsim tawm zoo tshaj plaws hauv kev sib txuas lus Fiber Option, tsuav yog them rau qhov ploj ntawm cov cim kho muag khoom hauv cov tshuab sib txuas lus. Tam sim no lub zog yog tam sim no cov cuab yeej siv dav tshaj plaws hauv kev sib txuas lus fiber ntau, muaj peev xwm kis tau cov cim tsis muaj zog.
