Tshawb nrhiav kev nce qib ntawmcolloidal quantum dot lasers
Raws li cov kev siv sib txawv, colloidal quantum dot lasers tuaj yeem muab faib ua ob pawg: optically pumped colloidal quantum dot lasers thiab hluav taws xob pumped colloidal quantum dot lasers. Hauv ntau qhov chaw xws li kev sim thiab kev lag luam,optically pumped lasers, xws li fiber ntau 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 ntawmoptical microflow laser, txoj kev laser raws li kev siv kho qhov muag yog qhov kev xaiv zoo tshaj plaws. Txawm li cas los xij, xav txog kev txav mus los thiab ntau yam kev siv, tus yuam sij rau daim ntawv thov ntawm colloidal quantum dot lasers yog kom ua tiav cov zis laser hauv qab hluav taws xob siv. Txawm li cas los xij, txog tam sim no, hluav taws xob twj tso kua mis colloidal quantum dot lasers tseem tsis tau paub. Yog li ntawd, nrog lub realization ntawm hluav taws xob twj tso kua mis colloidal quantum dot lasers raws li lub ntsiab kab, tus sau thawj zaug tham txog qhov tseem ceeb txuas ntawm tau txais hluav taws xob txhaj colloidal quantum dot lasers, uas yog, lub realization ntawm colloidal quantum dot nruam yoj optically pumped lasers, thiab ces. txuas mus rau lub colloidal quantum dot optically pumped tshuaj laser, uas yog heev yuav yog thawj zaug kom paub txog daim ntawv thov kev lag luam. Lub cev qauv ntawm kab lus no yog qhia hauv daim duab 1.
Muaj kev sib tw
Hauv kev tshawb fawb ntawm colloidal quantum dot laser, qhov kev sib tw loj tshaj yog tseem yuav ua li cas kom tau txais ib qho colloidal quantum dot nce nruab nrab nrog qis pib, siab nce, ntev nce lub neej thiab siab stability. Txawm hais tias cov qauv tshiab thiab cov ntaub ntawv xws li nanosheets, loj heev quantum dots, gradient gradient quantum dots, thiab perovskite quantum dots tau raug tshaj tawm, tsis muaj ib qho quantum dot tau lees paub nyob rau hauv ntau lub chaw soj nstuam kom tau txais kev nruam nthwv dej optically pumped laser, uas qhia tau tias qhov nce qib. thiab stability ntawm quantum dots tseem tsis txaus. Tsis tas li ntawd, vim tsis muaj cov qauv kev sib koom ua ke rau kev sib koom ua ke thiab kev ua tau zoo ntawm quantum dots, qhov nce kev ua tau zoo ntawm quantum dots los ntawm ntau lub teb chaws thiab cov chaw soj nstuam txawv heev, thiab kev rov ua dua tsis siab, uas tseem cuam tshuam txoj kev loj hlob ntawm colloidal quantum. dots nrog cov khoom muaj txiaj ntsig siab.
Tam sim no, quantum dot electropumped laser tsis tau pom dua, qhia tias tseem muaj cov kev sib tw hauv cov physics yooj yim thiab kev tshawb fawb thev naus laus zis tseem ceeb ntawm quantum dot.cov khoom siv laser. Colloidal quantum dots (QDS) yog cov khoom siv tau txais txiaj ntsig tshiab, uas tuaj yeem raug xa mus rau cov khoom siv hluav taws xob hluav taws xob ntawm cov organic teeb-emitting diodes (leds). Txawm li cas los xij, cov kev tshawb fawb tsis ntev los no tau pom tias kev siv yooj yim tsis txaus kom paub txog electroinjection colloidal quantum dot laser. Xav txog qhov sib txawv ntawm cov qauv hluav taws xob thiab kev ua haujlwm ntawm colloidal quantum dots thiab cov khoom siv organic, kev txhim kho cov txheej txheem tshiab cov yeeb yaj kiab npaj tsim nyog rau colloidal quantum dots thiab cov ntaub ntawv uas muaj hluav taws xob thiab qhov chaw thauj khoom yog tib txoj hauv kev kom paub cov electrolaser induced los ntawm quantum dots. . Qhov loj tshaj plaws colloidal quantum dot system tseem yog cadmium colloidal quantum dots uas muaj cov hlau hnyav. Xav txog kev tiv thaiv ib puag ncig thiab kev phom sij lom neeg, nws yog ib qho kev sib tw loj los tsim cov khoom siv laser quantum dot tshiab kom ruaj khov.
Hauv kev ua haujlwm yav tom ntej, kev tshawb fawb ntawm optically pumped quantum dot lasers thiab hluav taws xob twj quantum dot lasers yuav tsum sib koom tes thiab ua lub luag haujlwm tseem ceeb sib npaug hauv kev tshawb fawb thiab kev siv tswv yim. Nyob rau hauv cov txheej txheem ntawm kev siv ntawm colloidal quantum dot laser, ntau yam teeb meem yuav tsum tau daws sai sai, thiab yuav ua li cas muab tag nrho cov kev ua si rau cov khoom tshwj xeeb thiab kev ua haujlwm ntawm colloidal quantum dot tseem yuav tsum tau tshawb xyuas.
