Inkqubela phambili yophando lwecolloidal quantum dot lasers

Inkqubela yophando yecolloidal quantum dot lasers
Ngokweendlela zokumpompa ezahlukeneyo, iilaser zecolloidal quantum dot lasers zinokwahlulwa zibe ziindidi ezimbini: iilaser zecolloidal quantum dot ezimpompelwe ngombane kunye neelases zedothi ezimponthwe ngombane.Kwiinkalo ezininzi ezifana nelebhu kunye neshishini,iilaser ezimpontshwa nge-optically, ezifana ne-fiber lasers kunye ne-titanium-doped sapphire lasers, zidlala indima ebalulekileyo.Ukongeza, kwezinye iimeko ezithile, njengakwintsimi yelaser optical microflow, indlela ye-laser esekelwe kwi-optical pumping iyona nto ingcono kakhulu.Nangona kunjalo, ngokuqwalasela ukuphatheka kunye noluhlu olubanzi lwezicelo, isitshixo ekusetyenzisweni kwe-colloidal quantum dot lasers kukuphumeza i-laser output phantsi kokupompa kombane.Nangona kunjalo, kude kube ngoku, iilaser ze-colloidal quantum dot ezimponlwe ngombane azikaqatshelwa.Ke ngoko, ngokuqondwa kwecolloidal quantum dot lasers ezimpontshwe ngombane njengowona mgca uphambili, umbhali uqala axoxe ngekhonkco eliphambili lokufumana i-colloidal quantum dot lasers efakwe ngombane, oko kukuthi, ukufezekiswa kwe-colloidal quantum dot eqhubekayo yamaza optically pumped laser, emva koko. inabela kwicolloidal quantum dot optically pumped solution laser, ekusenokwenzeka ukuba ibe yeyokuqala ukuphumeza isicelo sorhwebo.Ukwakhiwa komzimba kweli nqaku kuboniswe kuMfanekiso 1.

Umngeni okhoyo
Kuphando lwe-colloidal quantum dot laser, owona mceli mngeni mkhulu useyindlela yokufumana i-colloidal quantum dot ukufumana okuphakathi kunye nomda ophantsi, inzuzo ephezulu, ukufumana ubomi obude kunye nokuzinza okuphezulu.Nangona izakhiwo zenoveli kunye nemathiriyeli enje ngeenanosheets, amachaphaza amakhulu e-quantum, amachaphaza e-gradient quantum, kunye namachaphaza e-perovskite quantum ziye zaxelwa, akukho ichaphaza elinye le-quantum liqinisekisiweyo kwiilebhu ezininzi zokufumana i-wave wave epompa i-laser, ebonisa ukuba umda wokuzuza. kunye nokuzinza kwamachaphaza e-quantum akwanelanga.Ukongeza, ngenxa yokunqongophala kwemigangatho edityanisiweyo yokudityaniswa kunye nokuchazwa kokusebenza kwamachaphaza e-quantum, iingxelo zentsebenzo yenzuzo yamachaphaza e-quantum evela kumazwe ahlukeneyo nakwiilabhoratri zahluke kakhulu, kwaye ukuphindaphinda akukho phezulu, nto leyo ikwathintela uphuhliso lwe-colloidal quantum. amachaphaza aneempawu zokuzuza okuphezulu.

Okwangoku, i-quantum dot electropumped laser ayikaziwa, nto leyo ebonisa ukuba kusekho imingeni kwifiziksi esisiseko kunye nophando oluphambili lwetekhnoloji yedot ye-quantum.izixhobo laser.Amachaphaza e-Colloidal quantum (QDS) sisisombululo esitsha sokufumana isisombululo, esinokubhekiswa kwisakhiwo sesixhobo se-electroinjection ye-organic light-emitting diodes (ii-leds).Nangona kunjalo, uphando lwakutsha nje lubonise ukuba ireferensi elula akwanelanga ukuqonda i-electroinjection colloidal quantum dot laser.Ukuqwalasela umahluko kwisakhiwo sombane kunye nemodi yokucubungula phakathi kwamachaphaza e-colloidal quantum kunye nezinto eziphilayo, ukuphuhliswa kweendlela ezintsha zokulungiswa kwefilimu ezilungele amachaphaza e-colloidal quantum kunye nezixhobo ezine-electron kunye nemisebenzi yokuthutha umngxuma yindlela yodwa yokuqonda i-electrolaser eyenziwa ngamachaphaza e-quantum. .Eyona nkqubo ikhulileyo yamachaphaza e-colloidal quantum isengamachaphaza e-cadmium colloidal quantum aqulethe iintsimbi ezinzima.Ukuthathela ingqalelo ukhuseleko lokusingqongileyo kunye neengozi zebhayoloji, ngumceli mngeni omkhulu ukuphuhlisa imathiriyeli entsha yecolloidal quantum dot laser.

Kumsebenzi wexesha elizayo, uphando lweelaser ze-quantum dot ezimponlwe ngombane kunye neelases ze-quantum dot ezimponlwe ngombane kufuneka zihambe kunye kwaye zidlale indima ebaluleke ngokulinganayo kuphando olusisiseko kunye nokusetyenziswa okusebenzayo.Kwinkqubo yokusetyenziswa okusebenzayo kwe-colloidal quantum dot laser, iingxaki ezininzi eziqhelekileyo kufuneka zisonjululwe ngokukhawuleza, kunye nendlela yokubonelela ngokudlala ngokupheleleyo kwiipropathi ezizodwa kunye nemisebenzi ye-colloidal quantum dot kusafuneka kuphononongwe.
