Mabone a LED a fetohile tharollo ea mabone a tloaelehileng bakeng sa malapa le likhoebo, empa LED ea setso e ngotse mefokolo ea bona ha ho tluoa tabeng ea lipontšo tse kholo, tse phahameng.Lipontšo tsa LEDsebelisa li-voltage tse phahameng 'me ntho e bitsoang matla a ka hare a ho fetola matla a tlase, ho bolelang hore litšenyehelo tsa matla tsa ho tsamaisa pontšo li holimo, bophelo ba pontšo ha bo bolelele, 'me bo ka chesa haholo.
Ka pampiri e phatlalalitsoeng ho Nano Research, bafuputsi ba hlalosa kamoo tsoelo-pele ea theknoloji e bitsoang matheba a quantum e ka sebetsanang le tse ling tsa mathata ana.Matheba a Quantum ke likristale tse nyane tsa maiketsetso tse sebetsang joalo ka li-semiconductors.Ka lebaka la boholo ba tsona, li na le thepa e ikhethang e ka etsang hore e be molemo ho theknoloji ea pontšo.
Xing Lin, motlatsi oa moprofesa oa saense ea tlhahisoleseding le boenjiniere ba elektroniki Univesithing ea Zhejiang, o itse setsoPontšo ea LEDba atlehile mafapheng a kang pontšo, mabone le puisano ea optical.Leha ho le joalo, mekhoa e sebelisoang ho fumana lisebelisoa le lisebelisoa tsa boleng bo holimo tsa semiconductor li nka matla haholo ebile li na le litšenyehelo tse ngata.Matheba a Colloidal quantum a fana ka mokhoa o theko e tlaase oa ho haha LED e sebetsang hantle ka ho sebelisa mekhoa e theko e tlaase ea ho lokisa tharollo le lisebelisoa tsa boemo ba lik'hemik'hale.Ho feta moo, joalo ka lisebelisoa tsa inorganic, matheba a colloidal quantum a feta li-semiconductors tsa organic ho latela botsitso ba ts'ebetso ea nako e telele.
Lipontšo tsohle tsa LED li entsoe ka mekhahlelo e mengata.Lera le leng la bohlokoahali ke lera le ntšang mosi, moo matla a motlakase a fetoloang khanya e mebala-bala.Bafuputsi ba sebelisitse lesela le le leng la matheba a quantum joalo ka lera la tlhahiso.Ka tloaelo, karolo ea colloidal quantum dot emission layer ke mohloli oa tahlehelo ea motlakase ka lebaka la ho se sebetse hantle ha colloidal quantum dot solids.Ka ho sebelisa lesela le le leng la matheba a quantum e le lesela le ntšang mosi, bafuputsi ba hakanya hore ba ka fokotsa motlakase ho fihlela holimo ho matlafatsa lipontšo tsena.
Tšobotsi e 'ngoe ea matheba a quantum a etsang hore a tšoanelehe bakeng sa LED ke hore a ka etsoa ntle le sekoli se ka amang ts'ebetso ea ona.Matheba a Quantum a ka etsoa ntle le litšila le bofokoli bo kaholimo.Ho ea ka Lin, quantum dot LED (QLED) e ka finyella katleho e haufi-ufi ea ho fetola matla a ka hare ho li-densities tsa hona joale tse loketseng bakeng sa lisebelisoa tsa pontšo le mabone.LED e tloaelehileng e ipapisitseng le li-semiconductors tse holileng ka nako e telele li bonts'a ts'ebetso e matla ka har'a mefuta e ts'oanang ea bongata ba hona joale.E ntle bakeng saIndasteri ea pontšo ea LED.Phapang ena e bakoa ke tlhaho e se nang sekoli ea matheba a boleng bo holimo a quantum.
Litšenyehelo tse batlang li le tlase tsa ho hlahisa lilae tse nang le matheba a mangata le bokhoni ba ho sebelisa mekhoa ea boenjineri ea optical ho ntlafatsa ts'ebetso ea khanya ea QLED, bafuputsi ba belaela, e ka ntlafatsa ka katleho LED ea setso e sebelisoang ho bonesa, lipontšo le tse ling.Empa ho ntse ho e-na le liphuputso tse ngata tse lokelang ho etsoa, 'me QLED ea morao-rao e na le mefokolo e lokelang ho hlōloa pele e ka amoheloa ka bongata.
Ho ea ka Lin, lipatlisiso li bontšitse hore matla a mocheso a ka ntšoa ho ntlafatsa katleho ea phetoho ea matla a electro-optical.Leha ho le joalo, ts'ebetso ea sesebelisoa mothating ona ha e ntle haholo ka kutloisiso ea li-voltages tse batlang li le holimo haholo le li-density tse tlase tsa hajoale.Mefokolo ena e ka hlōloa ka ho batla lisebelisoa tse betere tsa lipalangoang le ho rala khokahano lipakeng tsa lipalangoang tsa tefiso le matheba a quantum.Sepheo sa ho qetela-ho hlokomela lisebelisoa tsa ho pholisa ka electroluminescent-e lokela ho ba QLED-based.
