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 esiyinhloko sokuthola ama-laser e-colloidal quantum dot ajovwe ngogesi, okungukuthi, ukugcwaliseka kwe-colloidal quantum dot eqhubekayo futha i-laser optically pumped, bese idlulela ku-colloidal quantum isixazululo sokuqala ukuba yi-laser oquantum. ukuthola isicelo sokuhweba. 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 zamanoveli nezinto zokwakha ezinjengama-nanosheet, amachashazi e-quantum amakhulu, amachashazi e-gradient quantum, namachashazi e-perovskite quantum, alikho ichashazi elilodwa le-quantum eliqinisekisiwe kumalabhorethri amaningi ukuze kutholwe i-wave wave optically pumped laser, okubonisa ukuthi umkhawulo wokuzuza nokuqina kwamachashazi e-quantum kusewukwanele. Ngaphezu kwalokho, ngenxa yokuntuleka kwamazinga ahlanganisiwe okuhlanganiswa nokusebenza kwamachashazi we-quantum, imibiko yokusebenza kwenzuzo yamachashazi e-quantum evela emazweni ahlukene nasezilabhorethri ihluka kakhulu, futhi ukuphindaphinda akuphezulu, okuphinde kuvimbele ukuthuthukiswa kwamachashazi e-quantum e-colloidal anezakhiwo ezizuzisa kakhulu.
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 yesisombululo ezifanele amachashazi we-colloidal quantum nezinto zokuthutha ezine-electron kanye nemisebenzi yokuthutha imbobo kuwukuphela kwendlela yokubona i-electrolaser ebangelwa amachashazi e-quantum. Uhlelo oluvuthwe kakhulu lwamachashazi e-colloidal quantum kusengamachashazi 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.
