Inqubekelaphambili yocwaningo lwei-colloidal quantum dot lasers
Ngokwezindlela ezihlukene zokumpompa, amalaza echashazi e-colloidal quantum angahlukaniswa abe izigaba ezimbili: ama-laser amachashazi e-colloidal quantum ampontshwa ngogesi namalaser e-colloidal quantum dot.Emikhakheni eminingi efana nelabhorethri nezimboni,ama-lasers ampontshwa nge-optically, njengama-fiber lasers namalaser esafire enziwe nge-titanium, adlala indima ebalulekile.Ngaphezu kwalokho, kwezinye izimo ezithile, njengasensimini yeoptical microflow laser, indlela ye-laser esekelwe ekupompeni optical iyona engcono kakhulu.Kodwa-ke, uma kucatshangelwa ukuphatheka nobubanzi obubanzi bezinhlelo zokusebenza, ukhiye wokusetshenziswa kwamachashazi e-colloidal quantum dot ukuzuza ukuphuma kwe-laser ngaphansi kokumpompa ngogesi.Kodwa-ke, kuze kube manje, amachashazi e-colloidal quantum ampontshwa ngogesi awakenziwa.Ngakho-ke, ngokuqaphela amachashazi e-colloidal quantum dot ampontshwa ngogesi njengomugqa oyinhloko, umbhali uqale axoxe ngesixhumanisi esibalulekile sokuthola amachashazi e-colloidal quantum dot lasers, okungukuthi, ukugcwaliseka kwe-colloidal quantum dot wave wave optically pumped laser, bese emva kwalokho. idlulela ku-colloidal quantum dot optically pumped solution laser, okungenzeka kube ngeyokuqala ukwamukela ukusetshenziswa kwezentengiso.Isakhiwo somzimba salesi sihloko siboniswa kuMfanekiso 1.
Inselele ekhona
Ocwaningweni lwe-colloidal quantum dot laser, inselele enkulu kusewukuthi ungayithola kanjani i-colloidal quantum dot gain medium enomkhawulo ophansi, inzuzo ephezulu, impilo yesikhathi eside nokuzinza okuphezulu.Yize kubikiwe izakhiwo zenoveli nezinto zokwakha ezinjengama-nanosheet, amachashazi e-quantum amakhulu, amachashazi e-gradient quantum, namachashazi e-perovskite quantum, alikho ichashazi elilodwa eliqinisekisiwe kuma-laboratories amaningi ukuze kutholwe i-wave wave optically pumped laser, okukhombisa ukuthi umkhawulo wokuzuza. kanye nokuzinza kwamachashazi e-quantum akwanele.Ngaphezu kwalokho, ngenxa yokuntuleka kwamazinga ahlanganisiwe okuhlanganiswa nokusebenza kwamachashazi e-quantum, imibiko yokusebenza kwenzuzo yamachashazi e-quantum evela emazweni ahlukene nasezilabhorethri ihluka kakhulu, futhi ukuphindaphinda akuphakeme, okuphinde kuvimbele ukuthuthukiswa kwe-colloidal quantum. amachashazi anezindawo zokuzuza okuphezulu.
Okwamanje, i-quantum dot electropumped laser ayikatholakali, okubonisa ukuthi kusenezinselelo ku-basic physics kanye nocwaningo lobuchwepheshe olubalulekile lwechashazi le-quantum.amadivaysi laser.Amachashazi e-Colloidal quantum (QDS) ayinto entsha yenzuzo engacutshungulwa, engadluliselwa esakhiweni sedivayisi yokujova ugesi yama-organic light-emitting diode (ama-led).Kodwa-ke, ucwaningo lwakamuva lubonise ukuthi ukubhekisela okulula akwanele ukubona i-electroinjection colloidal quantum dot laser.Uma kucatshangelwa umehluko wesakhiwo se-elekthronikhi kanye nemodi yokucubungula phakathi kwamachashazi e-colloidal quantum nezinto eziphilayo, ukuthuthukiswa kwezindlela ezintsha zokulungiselela ifilimu ezilungele amachashazi we-colloidal quantum nezinto zokwakha ezine-electron nemisebenzi yokuthutha imbobo kuwukuphela kwendlela yokubona i-electrolaser ebangelwa amachashazi e-quantum. .Isistimu yamachashazi e-colloidal quantum evuthiwe isengamachashazi e-cadmium colloidal quantum aqukethe izinsimbi ezisindayo.Uma kucatshangelwa ukuvikelwa kwemvelo kanye nobungozi bebhayoloji, kuyinselelo enkulu ukwakha izinto ezintsha ze-colloidal quantum dot laser.
Emsebenzini wesikhathi esizayo, ucwaningo lwamalaza e-quantum dot ampontshwa ngogesi kanye namalaser amachashazi ampontshwa ngogesi kufanele ahambisane futhi adlale indima ebaluleke ngokulinganayo ocwaningweni oluyisisekelo nasekusetshenzisweni okungokoqobo.Enqubweni yokusetshenziswa okungokoqobo kwe-colloidal quantum dot laser, izinkinga eziningi ezivamile zidinga ukuxazululwa ngokuphuthumayo, kanye nendlela yokunikeza umdlalo ogcwele izici eziyingqayizivele nemisebenzi yechashazi le-colloidal quantum kusazobhekwa.
