Kafukufuku wa ma colloidal quantum dot lasers

Kupita patsogolo kwa kafukufuku wacolloidal quantum dot lasers
Malinga ndi njira zosiyanasiyana zopopera, ma laser a colloidal quantum dot amatha kugawidwa m'magulu awiri: ma lasers opopa madontho a colloidal quantum dot lasers opopedwa ndi magetsi a colloidal quantum dot. M'magawo ambiri monga labotale ndi mafakitale,ma lasers opangidwa ndi optically, monga ma fiber lasers ndi titaniyamu-doped sapphire lasers, akugwira ntchito yofunikira. Komanso, mu zochitika zina zenizeni, monga m'munda walaser kuwala kwa microflow, njira ya laser yochokera pakupopera kwa kuwala ndiyo yabwino kwambiri. Komabe, poganizira za kusuntha ndi ntchito zosiyanasiyana, chinsinsi chogwiritsa ntchito ma colloidal quantum dot lasers ndikukwaniritsa kutulutsa kwa laser pansi pa kupopera kwamagetsi. Komabe, mpaka pano, ma lasers opopa ma colloidal quantum dot dot sanazindikirike. Chifukwa chake, pakuzindikira kwa ma lasers opopa madontho a colloidal quantum dot monga mzere waukulu, wolemba akambirana kaye za ulalo wofunikira wopezera ma laser a colloidal quantum dot, ndiko kuti, kukwaniritsidwa kwa ma colloidal quantum dot mafunde opitilira apo amapopa laser, ndiyeno. imafikira ku laser colloidal quantum dot optically pumped solution, yomwe ikuyenera kukhala yoyamba kugwiritsa ntchito malonda. Maonekedwe a thupi la nkhaniyi akuwonetsedwa mu Chithunzi 1.

Vuto lomwe liripo
Pakafukufuku wa laser ya colloidal quantum dot, chovuta chachikulu ndikadali momwe mungapezere madontho a colloidal quantum omwe ali ndi malire otsika, kupindula kwakukulu, kupeza moyo wautali komanso kukhazikika kwakukulu. Ngakhale zolemba zatsopano ndi zida monga ma nanosheets, madontho akulu akulu, madontho a gradient quantum, ndi madontho a perovskite quantum zanenedwa, palibe dontho limodzi lokha lomwe latsimikiziridwa m'ma laboratories angapo kuti apeze laser yopitilira apopa, zomwe zikuwonetsa kuti phindu lochulukirapo. ndipo kukhazikika kwa madontho a quantum sikukwanira. Kuphatikiza apo, chifukwa chosowa miyezo yolumikizana yophatikizika ndi mawonekedwe a madontho a quantum, malipoti a kuchuluka kwa madontho ochokera kumaiko osiyanasiyana ndi ma labotale amasiyana kwambiri, ndipo kubwerezanso sikokwera, zomwe zimalepheretsanso kukula kwa colloidal quantum. madontho okhala ndi zopindulitsa kwambiri.

Pakadali pano, laser ya quantum dot electropumped laser sichinazindikiridwe, zomwe zikuwonetsa kuti padakali zovuta mu sayansi yoyambira komanso kafukufuku wofunikira waukadaulo wamadontho a quantum.zida za laser. Madontho a Colloidal quantum (QDS) ndi njira yatsopano yopezera phindu, yomwe ingatchulidwe ku chipangizo cha electroinjection cha organic light-emitting diode (maled). Komabe, kafukufuku waposachedwa wawonetsa kuti kutanthauzira kosavuta sikokwanira kuzindikira ma electroinjection colloidal quantum dot laser. Poganizira kusiyana kwa mawonekedwe amagetsi ndi makina opangira zinthu pakati pa madontho a colloidal quantum ndi zinthu zachilengedwe, kupanga njira zatsopano zokonzekera filimu zoyenera madontho a colloidal quantum ndi zida zokhala ndi ma elekitironi ndi ntchito zoyendera dzenje ndiyo njira yokhayo yodziwira electrolaser yoyendetsedwa ndi madontho a quantum. . Makina okhwima kwambiri a colloidal quantum dot akadali madontho a cadmium colloidal quantum okhala ndi zitsulo zolemera. Poganizira zachitetezo cha chilengedwe komanso zoopsa zachilengedwe, ndizovuta kwambiri kupanga zida zatsopano zokhazikika za colloidal quantum dot laser.

M'ntchito yamtsogolo, kafukufuku wa ma lasers opopa madontho a quantum ndi magetsi opopa madontho a quantum akuyenera kuyendera limodzi ndikugwiranso ntchito yofunika kwambiri pakufufuza koyambira ndi kugwiritsa ntchito koyenera. Pogwiritsira ntchito colloidal quantum dot laser, mavuto ambiri omwe amapezeka amayenera kuthetsedwa mwachangu, komanso momwe angaperekere sewero lathunthu kuzinthu zapadera ndi ntchito za colloidal quantum dot ziyenera kufufuzidwa.
