Iterambere ryubushakashatsi bwacolloidal kwant akadomo
Ukurikije uburyo butandukanye bwo kuvoma, colloidal kwant dot laseri irashobora kugabanywamo ibyiciro bibiri: guhitamo pompe ya colloidal kwant dot lazeri hamwe nu mashanyarazi yavomwe na colloidal kwant dot laseri. Mubice byinshi nka laboratoire n'inganda,Amashanyarazi, nka fibre ya fibre na titanium-dope ya safiro, bigira uruhare runini. Mubyongeyeho, mubintu bimwe byihariye, nko murwego rwaoptique ya microflow laser, uburyo bwa laser bushingiye kumpompe optique niyo guhitamo neza. Nyamara, urebye uburyo bworoshye kandi bwagutse bwa porogaramu, urufunguzo rwo gushyira mu bikorwa kwa kwanto dot laseri ni ukugera kuri laser munsi yo kuvoma amashanyarazi. Ariko, kugeza ubu, amashanyarazi yavomwe mu bwoko bwa colloidal kwant dot laseri ntabwo yabonetse. Kubwibyo, hamwe no kumenya amashanyarazi ya pompe yamashanyarazi nkumurongo wingenzi, umwanditsi yabanje kuganira kumurongo wingenzi wo kubona amashanyarazi yatewe mumashanyarazi ya colloidal kwant dot laseri, ni ukuvuga ko hamenyekanye kwaduka kwaduka yumudugudu ukomeza kuvoma lazeri, hanyuma hanyuma igera kuri colloidal kwantumwanya utudomo twapanze igisubizo laser, birashoboka cyane ko aribwo bwa mbere bwabonye ubucuruzi. Imiterere yumubiri wiyi ngingo irerekanwa mu gishushanyo 1.
Ikibazo kiriho
Mu bushakashatsi bwakozwe na colloidal kwant dot laser, imbogamizi nini iracyari uburyo bwo kubona akadomo ka colloidal dot yunguka hagati hamwe n’urwego ruto, inyungu nyinshi, inyungu ndende kandi itajegajega. Nubwo ibyubatswe hamwe nibikoresho nka nanosheets, utudomo twinshi twa kwant, utudomo twa gradient gradient, hamwe nududomo twa kwa perovskite, nta kadomo kamwe kamwe kemewe muri laboratoire nyinshi kugirango haboneke umurongo uhoraho wapompa lazeri, ibyo bikaba byerekana ko inyungu zinjira no gutuza kwadomo ya kwant iracyahagije. Byongeye kandi, kubera kubura ibipimo bihuriweho kugirango synthesis hamwe nimikorere iranga utudomo twa kwant, raporo zerekana inyungu zerekana utudomo twa kwant kuva mu bihugu bitandukanye na laboratoire ziratandukanye cyane, kandi gusubiramo ntabwo ari hejuru, ibyo bikaba binadindiza iterambere rya kwanto. Utudomo dufite inyungu nyinshi.
Kugeza ubu, kwaduka ya dot electropumped laser ntabwo byigeze bigerwaho, byerekana ko hakiri imbogamizi muri fiziki shingiro nubushakashatsi bwibanze bwikoranabuhanga rya kwant.ibikoresho bya laser. Utudomo twa colloidal (QDS) nigikoresho gishya gishobora gutunganyirizwa inyungu, gishobora koherezwa muburyo bwa electroinjection igikoresho cya diode kama itanga urumuri (leds). Nyamara, ubushakashatsi buherutse gukorwa bwerekanye ko ibintu byoroshye bidahagije kugirango umenye electroinjection colloidal kwant dot laser. Urebye itandukaniro ryimiterere yuburyo bwa elegitoronike nuburyo bwo gutunganya hagati yutudomo twa colloidal hamwe nibikoresho kama, guteza imbere uburyo bushya bwo gutegura firime yuburyo bukwiranye nuduce duto twa colloidal nibikoresho hamwe nibikorwa bya transport ya electron nu mwobo niyo nzira yonyine yo kumenya electrolaser iterwa nuduce twa kwant. . Sisitemu ya Quantum ikuze cyane iracyari cadmium colloidal utudomo turimo ibyuma biremereye. Urebye kurengera ibidukikije n’ingaruka z’ibinyabuzima, ni ikibazo gikomeye cyo guteza imbere ibikoresho bishya birambye bya colloidal kwant dot laser ibikoresho.
Mubikorwa biri imbere, ubushakashatsi bwakozwe na pompe ya dot lazeri na pompe yamashanyarazi yamashanyarazi bigomba kujyana kandi bigira uruhare runini mubushakashatsi bwibanze no mubikorwa bifatika. Muburyo bwo gushyira mubikorwa ifatika ya colloidal kwant dot laser, ibibazo byinshi bikunze gukemurwa byihutirwa, nuburyo bwo gutanga umukino wuzuye kumiterere yihariye nimirimo idasanzwe ya dotike ya colloidal iracyashakishwa.
