Kufambira mberi kwetsvagiridzo yecolloidal quantum dot lasers
Zvinoenderana neakasiyana nzira dzekupomba, colloidal quantum dot lasers inogona kukamurwa kuita mapoka maviri: optically pumped colloidal quantum dot lasers uye magetsi anopomba colloidal quantum dot lasers. Muminda yakawanda senge laboratori neindasitiri,optically pumped lasers, senge fiber lasers uye titanium-doped sapphire lasers, iri kutamba basa rakakosha. Mukuwedzera, mune mamwe mamiriro chaiwo, akadai semumunda weoptical microflow laser, iyo nzira yelaser yakavakirwa pane optical kupomba ndiyo yakanakisa sarudzo. Nekudaro, tichifunga nezve kutakurika uye kuwanda kwekushandisa, kiyi yekushandiswa kwecolloidal quantum dot lasers ndeyekuwana laser kubuda pasi pemagetsi kupomba. Nekudaro, kusvika zvino, magetsi akapombwa colloidal quantum dot lasers haasati aitwa. Naizvozvo, nekuzadzikiswa kwemagetsi akapombwa colloidal quantum dot lasers semutsetse mukuru, munyori anotanga ataura nezve kiyi link yekuwana magetsi akaiswa colloidal quantum dot lasers, ndiko kuti, kuitika kwecolloidal quantum dot inoenderera mberi wave optically pumped laser, uyezve. inosvika kune colloidal quantum dot optically pumped solution laser, iyo inogona kunge iri yekutanga kuona kushandiswa kwekutengesa. Mamiriro emuviri wechinyorwa ichi anoratidzwa muMufananidzo 1.
Dambudziko riripo
Mukutsvagisa kwecolloidal quantum dot laser, dambudziko rakakura nderekuti ungawana sei colloidal quantum dot kuwana svikiro ine yakaderera chikumbaridzo, kupfuma kukuru, kuwana hupenyu hurefu uye kugadzikana kwakanyanya. Kunyangwe zvinyowani zvimiro uye zvinhu zvakaita senanosheets, hofori quantum dots, gradient gradient quantum dots, uye perovskite quantum dots zvakashumwa, hapana imwechete quantum dot yakasimbiswa mumarabhoritari akawanda kuti iwane inoenderera mberi wave optically pumped laser, izvo zvinoratidza kuti chikumbaridzo chekuwana. uye kugadzikana kwe quantum dots haisati yakwana. Uye zvakare, nekuda kwekushaikwa kwemaitiro akabatana eiyo synthesis uye maitiro ekuita kwehuwandu dots, kuwana kwekuita mishumo yehuwandu hwemadotsi kubva kunyika dzakasiyana uye marabhoritari anosiyana zvakanyanya, uye kudzokorora hakuna kukwirira, izvo zvinotadzisa kuvandudzwa kwecolloidal quantum. madots ane high gain properties.
Parizvino, iyo quantum dot electropumped laser haisati yaitika, zvichiratidza kuti kuchine matambudziko mufizikisi yekutanga uye kiyi tekinoroji yekutsvaga yequantum dot.Laser zvishandiso. Colloidal quantum dots (QDS) mhinduro itsva-inogadziriswa kuwana zvinhu, iyo inogona kuendeswa kune electroinjection mudziyo chimiro cheorganic light-emitting diodes (leds). Nekudaro, ongororo dzichangoburwa dzakaratidza kuti chirevo chakareruka hachina kukwana kuona iyo electroinjection colloidal quantum dot laser. Tichifunga nezve mutsauko wekugadzirwa kwemagetsi uye maitiro ekugadzirisa pakati pecolloidal quantum dots uye organic zvinhu, kuvandudzwa kwemhinduro itsva yekugadzira firimu nzira dzakakodzera colloidal quantum dots uye zvinhu zvine erekitironi nemaburi ekufambisa mabasa ndiyo chete nzira yekuziva iyo electrolaser inokonzereswa ne quantum dots. . Iyo yakanyanya kukura colloidal quantum dot system ichiri cadmium colloidal quantum madotsi ane heavy metal. Tichifunga nezvekuchengetedzwa kwezvakatipoteredza uye njodzi dzebiological, idambudziko rakakura kugadzira nyowani yakagadzikana colloidal quantum dot laser zvinhu.
Mubasa remangwana, tsvakiridzo yeoptically pumped quantum dot lasers uye magetsi akapombwa quantum dot lasers anofanirwa kuenda pamwe chete uye kuita basa rakakosha zvakaenzana mukutsvagisa kwekutanga uye mashandisirwo anoshanda. Mukuita kwekuita kwekushandisa kwe colloidal quantum dot laser, matambudziko mazhinji akajairika anoda kugadziriswa nekuchimbidza, uye maitiro ekupa kutamba kwakazara kune yakasarudzika zvivakwa uye mabasa e colloidal quantum dot inoramba ichiongororwa.
