Tshiab quantum dot npaj tshuab kom meej tswj cov xim ntawm lub teeb yuav ua rau lub sijhawm tshiab ntawm LED teeb pom kev zoo
Jan 11, 2022
Science thiab Technology Txhua Hnub Xov Xwm, quantum dots tau muaj kev cuam tshuam loj rau kev lag luam ntawm LED thev naus laus zis, thiab tam sim no, kev txhim kho nws cov txheej txheem tsim khoom thiab nce cov txiaj ntsig yog qhov tseem ceeb ntawm kev tshawb fawb. Raws li tsab ntawv ceeb toom ntawm Spectroscopy lub vev xaib ntawm Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob thiab Hluav Taws Xob Hluav Taws Xob, cov kws tshawb fawb ntawm Oregon State University hauv Tebchaws Meskas tsis ntev los no tau nthuav tawm lub tshuab tshiab quantum dot manufacturing technology uas tsis tsuas yog ua kom qhov loj thiab cov duab ntawm cov khoom tsim quantum dots zoo ib yam. , tab sis kuj ntau meej xim tswj yuav txhais tau hais tias lub advent ntawm ib tug tshiab era ntawm LED teeb.
Hauv kev tshawb fawb luam tawm hauv" Phau ntawv Journal ntawm Nanoparticle Research", pab pawg tshawb fawb tau siv cov tshuaj reactor hu ua" txuas mus ntxiv". Cov tshuaj tsis tu ncua tau muab tso rau hauv lub reactor thiab tsim cov teeb pom kev zoo LED txuas ntxiv. Cov cuab yeej txuas mus tas li no ua rau cov txheej txheem ntawm kev tsim cov teeb pom kev zoo LED pheej yig dua, sai dua, thiab zoo heev. Nyob rau tib lub sijhawm, lawv siv microwaves los ua kom sov cov reagents, uas daws qhov teeb meem ntawm yuav ua li cas tswj qhov kub thiab txias hauv cov tshuaj tiv thaiv. Cov khoom siv microwave zoo li no ua haujlwm zoo ib yam li lub qhov cub microwave uas koj siv hauv tsev.
Cov kws tshawb fawb ntseeg tias txoj kev no yuav ua rau muaj kev hloov pauv loj heev hauv thaj chaw ntawm LED teeb pom kev zoo. Txij li txoj kev no tuaj yeem tsim cov quantum dots ntawm qhov loj me thiab cov duab zoo ib yam, nws qhov yooj yim ua kom ntseeg tau tias cov tuam ntxhab tuaj yeem tsim cov quantum dots nrog ntau yam kev siv. Cov quantum dots me tuaj yeem tawm lub teeb ntsuab, thiab cov quantum dots loj tuaj yeem tso cov txiv kab ntxwv rau lub teeb liab.
& quot; Tej zaum peb yuav thaum kawg tsim cov nqi qis, ua haujlwm siab LED teeb pom kev zoo, thiab tuaj yeem ua tiav cov txiaj ntsig ntawm lub teeb dawb lub teeb uas tib neeg xav tau," Greg Herman, tus kws tshaj lij ntawm chemical engineering ntawm lub tsev kawm ntawv tau hais. Pab neeg tshawb fawb ntseeg tias lawv txoj kev tsim khoom muaj tseeb tuaj yeem coj cov xim tswj tau zoo dua piv nrog lwm cov quantum dot manufacturing technologies.
& quot; Tib lub sijhawm, lub tshuab no siv cov ntaub ntawv tsis muaj tshuaj lom thiab txo cov khoom pov tseg, uas yuav txo cov nqi tsim khoom thiab tiv thaiv ib puag ncig." Herman piav qhia tias piv nrog cadmium feem ntau siv nyob rau hauv LED teeb pom kev zoo, quantum dots siv tooj liab indium diselenide cov ntaub ntawv sib xyaw yog ntau tus phooj ywg ib puag ncig.
Cov kws tshawb fawb tau hais tias quantum dots ua los ntawm txoj kev no tuaj yeem muab lwm" pheej yig" kev xaiv rau ntau yam xws li optics, electronics, thiab biomedicine.
