Inkqubela yophando lwe-colloidal quantum dot lasers

Inkqubela phambili yophandoiileza ze-colloidal quantum dot
Ngokweendlela ezahlukeneyo zokupompa, ii-colloidal quantum dot lasers zinokwahlulwa zibe ziindidi ezimbini: ii-optically pumped colloidal quantum dot lasers kunye nee-electrical pumped colloidal quantum dot lasers. Kwimimandla emininzi efana nelebhu kunye neshishini,iileser ezimpontshwe ngokubonakalayo, njengee-fiber lasers kunye nee-titanium-doped sapphire lasers, zidlala indima ebalulekileyo. Ukongeza, kwezinye iimeko ezithile, njengakwicandelo le-i-laser ye-microflow ebonakalayo, indlela yelaser esekelwe ekumpompeni nge-optical yeyona ndlela ilungileyo. Nangona kunjalo, xa sicinga ngokuphatheka lula kunye noluhlu olubanzi lwezicelo, isitshixo sokusetyenziswa kwee-colloidal quantum dot lasers kukufezekisa imveliso yelaser phantsi kokumpompa ngombane. Nangona kunjalo, kude kube ngoku, ii-colloidal quantum dot lasers ezimpompelwe ngombane azikaqatshelwa. Ke ngoko, ngokuphunyezwa kwee-colloidal quantum dot lasers ezimpompelwe ngombane njengomgca ophambili, umbhali uqala ngokuxoxa ngekhonkco eliphambili lokufumana ii-colloidal quantum dot lasers ezifakwe ngombane, oko kukuthi, ukufezekiswa kwe-colloidal quantum dot continuous wave optically pumped laser, aze emva koko andise kwi-colloidal quantum dot optically pumped laser, ekunokwenzeka ukuba ibe yeyokuqala ukuphumeza ukusetyenziswa kwezorhwebo. Ulwakhiwo lomzimba wale nqaku luboniswe kuMfanekiso 1.

Umngeni okhoyo
Kuphando lwe-colloidal quantum dot laser, owona mceli mngeni mkhulu usekukuba ungayifumana njani i-colloidal quantum dot gain medium ene-low threshold, i-high gain, i-long gain life kunye ne-high stability. Nangona kuye kwaxelwa ngezakhiwo ezintsha kunye nezixhobo ezifana nee-nanosheets, ii-giant quantum dots, ii-gradient gradient quantum dots, kunye nee-perovskite quantum dots, akukho dot enye ye-quantum eqinisekisiweyo kwiilabhoratri ezininzi ukuze kufunyanwe i-continuous wave optically pumped laser, nto leyo ebonisa ukuba i-gain threshold kunye ne-stability yee-quantum dots azanelanga. Ukongeza, ngenxa yokungabikho kwemigangatho edibeneyo yokwenziwa kunye nokuchazwa kokusebenza kwee-quantum dots, iingxelo ze-gain performance zee-quantum dots ezivela kumazwe ahlukeneyo nakwiilabhoratri zahlukile kakhulu, kwaye ukuphindaphindwa akuphezulu, nto leyo ethintela nophuhliso lwee-colloidal quantum dots ezineempawu ze-high gain.

Okwangoku, i-laser ye-quantum dot electropumped ayikafunyanwa, nto leyo ebonisa ukuba kusekho imingeni kuphando olusisiseko lwefiziksi kunye netekhnoloji ephambili ye-quantum dot.izixhobo zelaserAmachaphaza e-Colloidal quantum (QDS) zizinto ezintsha ezinokusetyenzwa ngesisombululo, ezinokubhekiswa kwisakhiwo sesixhobo se-electroinjection se-organic light-emitting diodes (LEDs). Nangona kunjalo, izifundo zakutshanje zibonise ukuba ukubhekisa okulula akwanelanga ukuqonda i-electroinjection colloidal quantum dot laser. Ukuqwalasela umahluko kwisakhiwo se-elektroniki kunye nendlela yokucubungula phakathi kwamachaphaza e-colloidal quantum kunye nezinto eziphilayo, uphuhliso lweendlela ezintsha zokulungiselela ifilimu yesisombululo ezifanelekileyo kumachaphaza e-colloidal quantum kunye nezinto ezinemisebenzi yokuthutha ye-electron kunye nomngxuma yindlela ekuphela kwayo yokufumana i-electrolaser ebangelwa ngamachaphaza e-quantum. Inkqubo ye-colloidal quantum dot evuthiweyo isengamachaphaza e-cadmium colloidal quantum equlethe iintsimbi ezinzima. Ukuqwalasela ukhuseleko lokusingqongileyo kunye neengozi zebhayoloji, ngumceli mngeni omkhulu ukuphuhlisa izinto ezintsha ze-colloidal quantum dot laser ezizinzileyo.

Kwixesha elizayo, uphando lwee-laser ze-quantum dot ezifakwe i-optically pumped kunye nee-laser ze-quantum dot ezifakwe i-electrically pumped kufuneka zihambisane kwaye zidlale indima ebaluleke ngokulinganayo kuphando olusisiseko kunye nokusetyenziswa okusebenzayo. Kwinkqubo yokusetyenziswa okusebenzayo kwe-colloidal quantum dot laser, iingxaki ezininzi eziqhelekileyo kufuneka zisonjululwe ngokukhawuleza, kwaye indlela yokunika indima epheleleyo kwiimpawu ezizodwa kunye nemisebenzi ye-colloidal quantum dot isafuneka ihlolwe.
