Utudomo twa Quantur na ext
Nkibikoresho bya Noven Nano, utudomo bwa Quafd (QDS) dufite imikorere idasanzwe kubera ingano yacyo. Imiterere yibi bikoresho ni spherical cyangwa quasi-spherical, na diameter yayo kuva 2nm kugeza 20nm. QDS ifite ibyiza byinshi, nko kwerekana ibintu byinshi byo kumvikana, kugenda bimaze kumvikana, ubuzima bunini bwa fluorescent, cyane cyane ibintu bya QDS birashobora gupfukirana urumuri rwose rugaragara binyuze mu guhindura ubunini bwayo.
Mu bisobanuro bitandukanye, ⅱ ~ ⅵ Qds yarimo CDSE yakoreshejwe cyane cyane kubisaba bitewe n'iterambere ryihuse. Igice cya kabiri cya ⅱ ~ ⅵ Qds kuva kuri 30nm kugeza kuri 50nm, kikaba kiri munsi ya synthesis iboneye, kandi ibirimi bya Fluorescence muri Synthesis bikurikirana hafi ya 100%. Icyakora, kuboneka kwa CD bigarukira ku iterambere rya QDS. Ⅲ ~ ⅴ qds idafite CD yatejwe imbere ahanini, umusaruro wa fluorescence wa ofaniel yibikoresho ugera kuri 70%. Igice cya kabiri cy'icyatsi cy'icyatsi kibisi / zns ni 40 ~ 50 nm, n'umucyo utukura urimo / zns ni 8 nm. Umutungo w'iki kikoresho ugomba kunozwa. Vuba aha, PAX3 Perovskite zidakeneye gupfukirana imiterere ya shell yakwegereye ibitekerezo byinshi. Uburebure bwa Oxrans muribo burashobora guhinduka mumucyo ugaragara byoroshye. Umusaruro wa Fluorescence wa Fleum wa Perovskite urenga 90%, kandi igice cya kabiri cya kabiri ni 15nm. Kubera ibara rya QDS luminescent ibikoresho birashobora kugera kuri 140% NTSC, ibi bikoresho bifite ibyifuzo byiza mubikoresho bya luyonecent. Porogaramu nyamukuru zarimo ko aho kuba isi idasanzwe yo kugurisha amatara ifite amabara n'amatara muri electrode yoroheje.
Qds yerekana ibara ryuzuye ritunganijwe kuri ibi bikoresho urashobora kubona uburebure bwumuyaga uwo ari wo wose mu gucana, ubugari bw'igice cy'umuhengeri kiri munsi ya 20nm. Qds ifite ibintu byinshi biranga, bikubiyemo gusohora ibara, speopr cubasrrum, fluorescence ya kaforem ya Quorefence. Barashobora gukoreshwa muguhitamo ibintu muri LCD Intara zikangirika zifatika na gamut ya LCD.
Uburyo bwo Gutandukanya QDs ni izi zikurikira:
1) ON-Chip: Ifu gakondo ya fluorescent isimburwa na Qds Ibikoresho bya Luumnescent, nuburyo nyamukuru bwo gutandukana bwa QDs mumirima yo gucana. Ibyiza byibi kuri chip ni umubare muto, kandi ibibi nibikoresho bigomba kugira umutekano mwinshi.
2) Kuri-hejuru: Imiterere ikoreshwa cyane mumatara. Filime ya Optique ikozwe muri qds, iri hejuru ya LGP muri blu. Ariko, igiciro kinini cyubuso bunini bwa filime ya optique bwagaruye porogaramu nini yubu buryo.
3) Ku nkombe: Ibikoresho bya QDS bikubiye mu murongo, kandi ugashyirwa kuruhande rwa strip ya LED na LGP. Ubu buryo bwagabanije ingaruka zimirasire yubushyuhe kandi optique iterwa nubururu bwayobowe na Qds Ibikoresho bya Luminescent. Byongeye kandi, gukoresha ibikoresho bya QDS nabyo biragabanuka.
