Quantum Dots uye Equipaplation
Sezvinoita novely nano zvinhu, iyo Quantum Dots (QDS) ine yakanakisa kuita nekuda kwehukuru hwayo. Chimiro chezvinhu izvi chinotenderera kana Quasi-sterical, uye dhayaudhi yeiyo inobva kune 2nm kusvika 20nm. QDS ine zvakawanda zvakanakira, zvakadzama spectation specttrum, hombe stokesenti yehupenyu, kunyanya biopicum yeQDs inogona kufukidza iyo yakazara yechiedza chikamu kuburikidza nekuchinja kwayo saizi.
Pakati pemamwe maQDs quinescent zvinhu, iyo ⅱ ~ q q ~ Iyo hafu-peak upamhi hweiyo ⅱ ~ qds inobva ku30nm kusvika pa50nm, iyo inogona kuve yakaderera kupfuura makumi matatu emamiriro ezvinhu akakodzera, uye iyo Fluorescence Quigem goho rasvika pane inosvika 100%. Nekudaro, kuvapo kweCD kushaikwa kukura kweQDS. Iyo ⅲ ~ qd isina CD yakagadziriswa zvakanyanya, iyo Fluorescence Quoduum goho rezvinyorwa izvi ndezve 70%. Iyo hafu-peak upamhi hwegreen light inp / zns ndeye 40 ~ 50 nm, uye iyo tsvuku mwenje inp / zns inenge 55 nm. Iyo pfuma yeiyi zvinhu inoda kuvandudzwa. Munguva pfupi yapfuura, iyo ABX3 Perovskites iyo isingade kufukidza iyo shell chimiro chakakwezva kutarisisa kwakawanda. Iyo Embimu Wavelength yeavo inogona kugadziriswa mune iyo muvhenekeri inooneka nyore. Iyo Fluorescence Quantum goverti yePerevskite inopfuura 90%, uye hafu-peak-peak upamhi hwanyana anenge 15nm. Nekuda kwerudzi rwegamari yeQDs Luminescent zvinhu zvinogona kusvika pa140% NTSC, iyi mhando yezvishandiso zvine zvikumbiro zvikuru muLuminescent mudziyo. Zvishandiso zvakakosha zvinosanganisira iyo pane isingawanzo nyika phosphor kuti vaone magetsi ane mavara mazhinji uye maronda mumhando yakaonda-firimu magetsi.
QDS inoratidza iyo yakagadziriswa mavara ekuti pane izvi zvinogona kuwana iyo spectrum ine chero urefu hwekuzara mumunda wechiedza, iyo hafu yehupamhi yehurefu hwakareba kupfuura 20nm. Iyo QDS ine zvakawanda zvehunhu, izvo zvaisanganisira shanduko yekubvisa ruvara, yakatetepa yekubuda spectrum, yakakwira fluorescence enthantum gohwo. Ivo vanogona kushandiswa kuti vaburitse spectrum muLCD kumashure uye kuvandudza iyo color inoratidzira simba uye gamut ye lcd.
Encapsigulation nzira dzeQDs dzinotevera:
1) ON-CHIP: Iyo yechinyakare fluorescent poda inotsiviwa neQD Luminescent zvinhu, iyo ndiyo nzira huru yekuchinja kweQDs mumunda wakareruka. Iko mukana weizvi paChip ndeye mashoma ezvinhu, uye kusagadzikana ndiko kuzvidzora kunofanirwa kuve nekugadzikana kwakanyanya.
2) On-pamusoro: Iyo chimiro inonyanya kushandiswa mukudzokera kumashure. Iyo firimu renyaya yakagadzirwa neQDS, iyo iri pamusoro peLGP muBlu. Nekudaro, iyo yakanyanya mutengo yenzvimbo yakakura yeye Optical firimu yakamanikana yakawandisa yekushandisa nzira iyi.
3) On-pamucheto: Iyo QDS yeQDS inokandirwa kubvarura, uye inoiswa padivi yeiyo LED Strip naLgp. Iyi nzira yakadzora mhedzisiro yemahombekombe uye optical radiation iyo inokonzerwa nebhuruu inotungamirwa uye qds luminescent zvinhu. Uyezve, kushandiswa kwemidziyo yeQDS zvakare yakaderera.
