Hloov ib-txhiab ntawm cov hmoov txhuas atom nrog manganese tuaj yeem nce peb zaug luminescence ntawm halide perovskite quantum tsuas me me. Pab pawg neeg tshawb fawb thoob ntiaj teb tau tsim cov thev naus laus zis tshiab uas tuaj yeem siv los ua kom cov nqi qis dua luminescent cov ntaub ntawv pauv tau yooj yim thiab tuaj yeem luam tawm siv tshuab inkjet.
Cov kws tshawb nrhiav los ntawm University of Cambridge hauv tebchaws Askiv thiab Lub Tsev Kawm Ntawv Technical ntawm Munich hauv tebchaws Yelemes pom tias los hloov ib-txhiab ntawm cov hmoov txhuas ua nrog manganese, lawv tuaj yeem nce peb zaug luminescence ntawm halide perovskite quantum dots.
Qhov doping no ua rau cov tseev kom them nqi thauj khoom mus tau daig hauv qee qhov ntawm cov khoom siv' s qauv siv lead ua, qhov chaw uas lawv tau tso tawm thiab xa teeb. Cov kev tshawb pom tau luam tawm nyob rau hauv phau ntawv Journal of the American Chemical Society thiab tuaj yeem siv rau cov nqi qis luam tawm thiab yoog raws LED teeb pom kev zoo, cov xov tooj ntse lossis cov lasers pheej yig.
.
Cov kws tshawb nrhiav los ntawm University of Cambridge tau koom tes nrog Dan Congreve pab pawg ntawm Harvard University hauv Tebchaws Meskas. Lawv yog cov kws tshaj lij hauv kev tsim cov khoom me me.
Cov kev tshawb nrhiav ncauj lus kom ntxaws uas siv cov duab laser spectroscopy qhia tawm lub hauv paus chiv keeb ntawm qhov kev soj ntsuam no." Peb pom tias kev them nqi hluav taws xob tau sib xyaw ua ke hauv peb cov cheeb tsam doped siv lead ua," hais tias Sascha Feldmann ntawm Cavendish Laboratory hauv Cambridge, thawj tus sau ntawm txoj kev tshawb no." Thaum muab tso rau, cov kev siv hluav taws xob ntau no tuaj yeem sib ntsib thiab sib zog ua kom lub teeb nyob rau hauv txoj kev siv tau zoo."
& quot; Peb cia siab tias qhov kev tshawb pom zoo no: Txawm tias cov kev hloov pauv me me rau cov tshuaj lom neeg lub cev muaj peev xwm ua tau ntau yam kev ua tau zoo ntawm cov khoom, uas yuav pua txoj hauv kev rau pheej yig thiab ultra-ci LED cov lus thiab lasers nyob rau yav tom ntej." Cov kws sau ntawv qib siab ntev hauv Felix Deschler tau hais tias nws tau ua haujlwm ua ke ntawm Cavendish thiab Walter Schottky Lub Tsev Kawm Ntawv ntawm Lub Tsev Kawm Txuj Ci ntawm Munich.
Yav tom ntej, cov kws tshawb nrhiav vam tias yuav nrhiav tau cov tshuaj dopants kom tau txais txiaj ntsig zoo dua, uas yuav pab ua kom cov kev tsim kho tshiab zoo tshaj plaws thoob plaws ntiaj teb.
