Amatara ya LED yahindutse igisubizo kiboneka hose kumazu no mubucuruzi, ariko LED gakondo yanditseho amakosa yabo mugihe kinini kinini, cyerekanwe cyane.LED yerekanakoresha voltage ndende nibintu byitwa imbaraga zo guhindura imikorere imbere ni bike, bivuze ko ikiguzi cyingufu zo gukoresha ibyerekanwa ari kinini, ubuzima bwo kwerekana ntabwo ari burebure, kandi burashobora gukora cyane.
Mu mpapuro zasohotse mu bushakashatsi bwa Nano, abashakashatsi bagaragaza uburyo iterambere ry’ikoranabuhanga ryitwa utudomo duto dushobora gukemura bimwe muri ibyo bibazo.Utudomo twa Quantum ni kristu ntoya ikora nka semiconductor.Bitewe nubunini bwabo, bafite imitungo idasanzwe ishobora gutuma iba ingirakamaro muburyo bwo kwerekana ikoranabuhanga.
Xing Lin, umwungirije wungirije ushinzwe ubumenyi n’ikoranabuhanga muri kaminuza ya Zhejiang, yavuze ko gakondoLED yerekanazatsinze mubice nko kwerekana, kumurika no gutumanaho neza.Nyamara, tekinoroji ikoreshwa kugirango ibone ibikoresho byujuje ubuziranenge bya semiconductor nibikoresho bikoresha ingufu nyinshi kandi bisaba amafaranga menshi.Utudomo twa colloidal dutanga uburyo buhendutse bwo kubaka LED ikora neza hakoreshejwe uburyo buhendutse bwo gutunganya ibisubizo hamwe nibikoresho byo mu rwego rwa shimi.Ikigeretse kuri ibyo, nkibikoresho bidakoreshwa, utudomo twa colloidal twumwanya urenze emissive organic semiconductor ukurikije igihe kirekire cyimikorere.
LED yerekana yose igizwe nibice byinshi.Kimwe mubyingenzi byingenzi ni emissive layer, aho ingufu z'amashanyarazi zihinduka urumuri rwamabara.Abashakashatsi bifashishije urwego rumwe rw'uduce duto twa kwant.Ubusanzwe, kwaduka kwaduka ya colloidal niyo ntandaro yo gutakaza imbaraga za voltage kubera ubushobozi buke bwa colloidal kwant dot solide.Mugukoresha urwego rumwe rw'utudomo twa kwant nka emissive layer, abashakashatsi bavuga ko zishobora kugabanya voltage kugeza kuri nini kugirango imbaraga zerekanwe.
Ikindi kintu kiranga akadomo ka kwantuma keza kuri LED nuko ishobora gukorwa nta nenge nimwe yagira ingaruka kumikorere yabo.Utudomo twa Quantum turashobora gushushanywa nta mwanda nubuso bwubuso.Nk’uko Lin abivuga, akadomo ka LED (QLED) karashobora kugera hafi yubumwe bwimbaraga zimbere zihinduranya imbaraga zubu zikwiranye no kwerekana no kumurika.LED isanzwe ishingiye ku gice cya kabiri cya semiconductor ikura yerekana imikorere ikabije mu ntera imwe.Nibyiza kuriInganda zerekana LED.Iri tandukanyirizo rituruka ku miterere-yubusa idafite ubuziranenge bwa kwant.
Abaguzi bakeka ko igiciro gito ugereranije no gutanga ibyuka bisohora bifite akadomo ka kwant hamwe nubushobozi bwo gukoresha tekiniki yubuhanga bwa optique kugirango hongerwe ingufu zo gukuramo urumuri rwa QLED, abashakashatsi bakeka ko bishobora guteza imbere LED gakondo ikoreshwa mumatara, kwerekana, nibindi byinshi.Ariko haracyariho ubushakashatsi bwinshi bugomba gukorwa, kandi QLED y'ubu ifite ibitagenda neza bigomba kuneshwa mbere yuko byemerwa cyane.
Ku bwa Lin, ubushakashatsi bwerekanye ko ingufu z’ubushyuhe zishobora gukururwa kugira ngo imikorere y’amashanyarazi ihindurwe neza.Nyamara, imikorere yibikoresho muriki cyiciro ni kure yicyiza muburyo bwo hejuru ya voltage ikora cyane hamwe nubucucike buriho.Izi ntege nke zirashobora kuneshwa mugushakisha ibikoresho byo gutwara ibintu neza no gushushanya intera iri hagati yubwikorezi bwamafaranga na kwant dot.Intego nyamukuru-yo kumenya ibikoresho byo gukonjesha electroluminescent-bigomba kuba bishingiye kuri QLED.
