Kev tshawb fawb txog kev nce qib ntawm colloidal quantum dot lasers

Kev tshawb fawb txog kev nce qib ntawmcov laser colloidal quantum dot
Raws li cov txheej txheem twj sib txawv, colloidal quantum dot lasers tuaj yeem muab faib ua ob pawg: optically pumped colloidal quantum dot lasers thiab electrically pumped colloidal quantum dot lasers. Hauv ntau qhov chaw xws li chav kuaj thiab kev lag luam,cov lasers uas siv lub tshuab optically pumped, xws li fiber lasers thiab titanium-doped sapphire lasers, tab tom ua lub luag haujlwm tseem ceeb. Tsis tas li ntawd, hauv qee qhov xwm txheej tshwj xeeb, xws li hauv thaj chaw ntawmlaser microflow kho qhov muag, txoj kev laser raws li kev siv lub twj tso kua mis optical yog qhov kev xaiv zoo tshaj plaws. Txawm li cas los xij, xav txog qhov yooj yim nqa thiab ntau yam kev siv, qhov tseem ceeb rau kev siv cov colloidal quantum dot lasers yog kom ua tiav cov zis laser hauv qab kev siv hluav taws xob. Txawm li cas los xij, txog tam sim no, cov colloidal quantum dot lasers uas siv hluav taws xob tsis tau paub txog. Yog li ntawd, nrog rau kev paub txog cov colloidal quantum dot lasers uas siv hluav taws xob ua kab tseem ceeb, tus sau thawj zaug tham txog qhov txuas tseem ceeb ntawm kev tau txais cov colloidal quantum dot lasers uas siv hluav taws xob, uas yog, kev paub txog cov colloidal quantum dot txuas ntxiv mus rau cov laser uas siv hluav taws xob, thiab tom qab ntawd txuas mus rau cov colloidal quantum dot optically pumped solution laser, uas yuav yog thawj zaug kom paub txog kev siv lag luam. Lub cev qauv ntawm tsab xov xwm no tau qhia hauv Daim Duab 1.

Kev sib tw uas twb muaj lawm
Hauv kev tshawb fawb ntawm colloidal quantum dot laser, qhov kev sib tw loj tshaj plaws tseem yog yuav ua li cas kom tau txais colloidal quantum dot gain medium nrog qhov qis qis, qhov nce siab, lub neej ntev thiab kev ruaj khov siab. Txawm hais tias cov qauv tshiab thiab cov ntaub ntawv xws li nanosheets, giant quantum dots, gradient gradient quantum dots, thiab perovskite quantum dots tau tshaj tawm, tsis muaj ib qho quantum dot tau lees paub hauv ntau lub chaw soj nstuam kom tau txais cov laser txuas ntxiv mus tas li, uas qhia tau tias qhov nce qib thiab kev ruaj khov ntawm quantum dots tseem tsis txaus. Tsis tas li ntawd, vim tsis muaj cov qauv sib koom ua ke rau kev sib xyaw thiab kev ua tau zoo ntawm quantum dots, cov ntawv qhia txog kev ua tau zoo ntawm quantum dots los ntawm ntau lub tebchaws thiab chaw soj nstuam sib txawv heev, thiab qhov rov ua dua tsis siab, uas kuj cuam tshuam kev txhim kho ntawm colloidal quantum dots nrog cov khoom nce siab.

Tam sim no, lub quantum dot electropumped laser tseem tsis tau paub, qhia tias tseem muaj kev cov nyom hauv kev tshawb fawb txog physics thiab kev tshawb fawb tseem ceeb ntawm quantum dot.cov khoom siv laser. Colloidal quantum dots (QDS) yog cov khoom siv tshiab uas ua tau raws li cov txheej txheem daws teeb meem, uas tuaj yeem xa mus rau cov qauv khoom siv electroinjection ntawm cov teeb pom kev zoo organic (leds). Txawm li cas los xij, cov kev tshawb fawb tsis ntev los no tau qhia tias kev siv yooj yim tsis txaus los ua kom pom cov electroinjection colloidal quantum dot laser. Xav txog qhov sib txawv ntawm cov qauv hluav taws xob thiab hom kev ua tiav ntawm colloidal quantum dots thiab cov ntaub ntawv organic, kev tsim cov txheej txheem npaj zaj duab xis daws teeb meem tshiab uas haum rau colloidal quantum dots thiab cov ntaub ntawv nrog cov haujlwm thauj hluav taws xob thiab qhov yog tib txoj hauv kev los ua kom pom cov electrolaser uas tshwm sim los ntawm quantum dots. Lub kaw lus colloidal quantum dot uas paub tab tshaj plaws tseem yog cadmium colloidal quantum dots uas muaj cov hlau hnyav. Xav txog kev tiv thaiv ib puag ncig thiab kev phom sij ntawm lub cev, nws yog qhov nyuaj heev los tsim cov khoom siv laser colloidal quantum dot tshiab.

Hauv kev ua haujlwm yav tom ntej, kev tshawb fawb ntawm cov lasers quantum dot uas siv optically pumped thiab cov lasers quantum dot uas siv hluav taws xob pumped yuav tsum mus ua ke thiab ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb yooj yim thiab kev siv tswv yim. Hauv cov txheej txheem ntawm kev siv colloidal quantum dot laser, ntau yam teeb meem uas tshwm sim yuav tsum tau daws sai sai, thiab yuav ua li cas muab kev ua si tag nrho rau cov khoom tshwj xeeb thiab kev ua haujlwm ntawm colloidal quantum dot tseem yuav tsum tau tshawb nrhiav.
