Amachashazi e-Quantum kanye ne-encapsulation
Njengento yenoveli ye-nano, amachashazi e-quantum (QDs) anokusebenza okuvelele ngenxa yobubanzi bawo bosayizi.Umumo wale nto uyindilinga noma i-quasi-spherical, futhi ububanzi bayo busuka ku-2nm kuye ku-20nm.Ama-QD anezinzuzo eziningi, njenge-spectrum ye-excitation ebanzi, i-spectrum ephumayo emincane, ukunyakaza okukhulu kwe-Stokes, isikhathi eside sempilo ye-fluorescent kanye nokuvumelana okuhle kwe-biocompatibility, ikakhulukazi i-spectrum ephumayo yama-QD ingamboza lonke ububanzi bokukhanya obubonakalayo ngokushintsha usayizi wayo.
Phakathi kwezinto ezihlukile ze-QDs luminescent, ama-QD angu-Ⅱ~Ⅵ afaka i-CdSe asetshenziswe ezinhlelweni eziningi ngenxa yokuthuthuka kwawo ngokushesha.Ububanzi besilinganiso esiphakeme esinguhhafu se-Ⅱ~Ⅵ QDs busuka ku-30nm kuye ku-50nm, obungaba ngaphansi kuka-30nm ezimeni ezifanele zokuhlanganisa, futhi isivuno se-fluorescence quantum sazo sicishe sifinyelele ku-100%.Nokho, ukuba khona kwe-Cd kwakhawulela ukuthuthukiswa kwama-QD.Ama-QD angu-Ⅲ~Ⅴ angenayo i-Cd athuthukiswe kakhulu, isivuno se-fluorescence quantum sale nto singama-70%.Ububanzi besiqongo sohhafu bokukhanya okuluhlaza i-InP/ZnS bungu-40~50 nm, futhi ukukhanya okubomvu kwe-InP/ZnS cishe ku-55 nm.Impahla yalesi sici idinga ukuthuthukiswa.Muva nje, i-ABX3 perovskites engadingi ukumboza isakhiwo segobolondo idonse ukunaka okukhulu.Ubude begagasi bawo bungalungiswa ekukhanyeni okubonakalayo kalula.Isivuno se-fluorescence quantum se-perovskite singaphezu kuka-90%, kanti ububanzi besigamu-sobukhulu bucishe bube ngu-15nm.Ngenxa ye-gamut yombala we-QDs luminescent materials ingafika ku-140% NTSC, lolu hlobo lwezinto zokwakha lusebenza kahle kudivayisi ye-luminescent.Izinhlelo zokusebenza eziyinhloko zazihlanganisa ukuthi esikhundleni se-phosphor yomhlaba engavamile ukukhipha izibani ezinemibala eminingi nokukhanyisa kuma-electrode amafilimu amancane.
Ama-QD akhombisa umbala okhanyayo ogcwele ngenxa yalesi sici angathola i-spectrum nganoma yibuphi ubude begagasi endaweni yokukhanyisa, leyo ububanzi obuyingxenye yobude begagasi bungaphansi kuka-20nm.Ama-QD anezici eziningi, ezihlanganisa umbala okhiphayo olungisekayo, i-spectrum ekhishwayo emincane, isivuno esiphezulu se-fluorescence quantum.Angasetshenziswa ukuthuthukisa i-spectrum kumalambu angemuva e-LCD futhi athuthukise amandla okuveza umbala kanye ne-gamut ye-LCD.
Izindlela zokuhlanganisa ama-QD zimi kanje:
1）Ku-chip:impushana yendabuko ye-fluorescent ithathelwa indawo yizinto ze-luminescent ze-QDs, okuyindlela eyinhloko ye-encapsulation yama-QD emkhakheni wokukhanyisa.Inzuzo yalokhu ku-chip inani elincane lezinto, kanti okubi ukuthi izinto kufanele zibe nokuzinza okuphezulu.
2）Okungaphezulu:isakhiwo sisetshenziswa kakhulu ekukhanyeni kwangemuva.Ifilimu yokubona yenziwe ngama-QD, engaphezulu kanye kwe-LGP ku-BLU.Kodwa-ke, izindleko eziphakeme zendawo enkulu yefilimu ye-optical zikhawulela ukusetshenziswa okubanzi kwale ndlela.
3）Onqenqemeni: izinto ze-QD zimbozwe ukuze zihlubule, futhi zibekwe eceleni komugqa we-LED kanye ne-LGP.Le ndlela inciphise imiphumela yemisebe eshisayo neyokukhanya ebangelwa i-LED eluhlaza okwesibhakabhaka kanye ne-QDs luminescent materials.Ngaphezu kwalokho, ukusetshenziswa kwezinto ze-QDs nakho kwehlile.
