Amachashazi we-Quantum kanye ne-Encoption
Njenge-Novel Nano impahla, amachashazi we-quantum (qd) asebenza kahle ngenxa yobubanzi bawo. Ukwakheka kwalokhu okuqukethwe kuyindilinga noma i-quasi-spherical, futhi ububanzi bawo buqala kusuka ku-2nm kuya ku-20nm. I-Qds inezinzuzo eziningi, ezinjengezinzuzo ezibanzi zokuxoxa, ukunyakaza okukhulu kokuphuma, isikhathi eside se-fluores, ikakhulukazi ukuthambekela kokuphuma kwe-qds kwama-qds kungasibekela lonke uhla olubonakalayo ngokushintsha usayizi walo.
Phakathi kwezinto ezahlukahlukene ezahlukahlukene ze-QDs Luminescent, i-ⅱ ~ Ububanzi obuphakeme bobubanzi be-ⅱ ~ ~ dds bura kusuka ku-30nm kuya ku-50nm, okungaba ngaphansi kwama-30nm ezimeni ezifanele ze-synthesis, kanye nesivuno se-fluorescence quantum sazo cishe kufinyelela ku-100%. Kodwa-ke, ukuba khona kwe-CD kukhawulelwe ukuthuthukiswa kwe-QD. I-ⅲ ~ ⅴ qd engenakho i-CD yathuthukiswa kakhulu, isivuno se-fluorescence quantum salokhu okuqukethwe cishe kungama-70%. Ububanzi obuphakeme obuphakeme bokukhanya okuluhlaza kwe-INP / ZNS ngu-40 ~ 50 nm, futhi ukukhanya okubomvu kwe-INP / ZNS kucishe kube ngu-55 nm. Impahla yalolu bhalimba idinga ukwenziwa ngcono. Muva nje, ama-perovskites e-ABX3 angadingi ukumboza isakhiwo segobolondo adonsele ukunakwa okuningi. I-Emition Wavelength yazo ingashintshwa ekukhanyiseni okubonakalayo kalula. Isivuno se-Fleorescence quantum se-perovskite singaphezu kwama-90%, futhi ububanzi be-Half-Peak bucishe bube ngu-15nm. Ngenxa ye-gamut yombala ye-QD luminescent izinto ezingafinyelela ku-140% NTSC, lolu hlobo lwezinto zokwakha lunezicelo ezinhle kudivayisi ye-luminescent. Izicelo ezisemqoka zifaka lokho esikhundleni se-phosphor yaseMhlabeni engavamile ukuvela amalambu anemibala eminingi nokukhanya ku-electrodes emincane.
I-QDS ikhombisa umbala ogcwele okhanyayo ngenxa yalokhu okubonakalayo kungathola ububanzi obunobude obunegagasi enkundleni yokukhanyisa, okuyingxenye yobubanzi obude obungaphansi kwe-20nm. Ama-qs anezici eziningi, efaka umbala oguqukayo wokufakelwa, imibala emincane yokuphuma, isivuno esiphakeme se-fluorescence. Zingasetshenziselwa ukwandisa i-spectrum ku-LCD backights futhi zithuthukise umbala ocacile kanye ne-gamut ye-LCD.
Izindlela ze-Eccopsetion ze-QDS zimi ngokulandelayo:
1) ku-chip: I-fluorescent yendabuko ithathelwa indawo izinto zokwakha ze-QDs, okuyizindlela eziphambili ze-EcASAStion ze-QDs enkundleni yokukhanyisa. Inzuzo yalokhu ku-chip inengxenye embalwa yento, futhi ubunzima bokuthi izinto zokwakha kumele zibe nokuqina okuphezulu.
2) On-Surce: Isakhiwo sisetshenziswa ikakhulukazi ekwamukeni. Ifilimu ebonakalayo yenziwa nge-QDS, okulungile ngenhla kwe-LGP ku-BLU. Kodwa-ke, izindleko eziphezulu zendawo enkulu yefilimu ebonakalayo zikhawulezelele ukusetshenziswa okubanzi kwale ndlela.
3) On-onqenqemeni: Izinto ze-QDS zifakwe ku-strip, futhi zibekwe ohlangothini lwe-LED strip ne-LGP. Le ndlela inciphise imiphumela yemisebe eshisayo ne-optical edalwa yizinto zokwakha eziluhlaza okwesibhakabhaka kanye ne-qs. Ngaphezu kwalokho, ukusetshenziswa kwezinto zokwenziwa kwe-qds nakho kuncishisiwe.
