Iterambere ry'ubushakashatsi kuri lasers za quantum dot

Intambwe ubushakashatsi bwateyelaser za quantum dot lasers
Dukurikije uburyo butandukanye bwo gupompa, laser za colloidal quantum dot lasers zishobora kugabanywamo ibice bibiri: laser za colloidal quantum dot lasers zikoreshwa mu buryo bw'ikoranabuhanga na laser za colloidal quantum dot lasers zikoreshwa mu buryo bw'amashanyarazi. Mu nzego nyinshi nka laboratwari n'inganda,lasers zikoresha ikoranabuhanga, nka fibre lasers na titanium-doped safiro lasers, bigira uruhare runini. Byongeye kandi, mu bihe bimwe na bimwe byihariye, nko mu rwego rwalaser y'urujya n'uruza rw'amatara, uburyo bwa laser bushingiye ku gupompa kw'amatara ni bwo bwiza kurusha ubundi. Ariko, ukurikije uburyo bworoshye bwo kohereza no gukoresha uburyo butandukanye, ingenzi mu gukoresha laser za colloidal quantum dot ni ukugera ku musaruro wa laser munsi yo gupompa amashanyarazi. Ariko, kugeza ubu, laser za colloidal quantum dot laser zikoreshwa n'amashanyarazi ntiziragerwaho. Kubwibyo, hamwe no kubona laser za colloidal quantum dot laser zikoreshwa n'amashanyarazi nk'umurongo nyamukuru, umwanditsi abanza kuvuga ku isano nyamukuru yo kubona laser za colloidal quantum dot laser zishyirwa mu matara, ni ukuvuga, gukora laser ya colloidal quantum dot continuous wave optically pumped, hanyuma akagera kuri laser ya colloidal quantum dot optically pumped, ishobora kuba iya mbere mu gukoreshwa mu bucuruzi. Imiterere y'umubiri w'iyi nkuru igaragazwa ku Ishusho ya 1.

Ikibazo gihari
Mu bushakashatsi bwa laser ya colloidal quantum dot, ikibazo gikomeye kiracyari uburyo bwo kubona colloidal quantum dot gain medium ifite threshold low, high gain, long gain life and high stability. Nubwo imiterere mishya n'ibikoresho nk'amashusho ya nano, dots nini za quantum, gradient gradient quantum dots, na perovskite quantum dots byagaragaye, nta dots na imwe ya quantum yemejwe muri laboratwari nyinshi kugira ngo haboneke laser ikomeza gukoreshwa, ibi bigaragaza ko threshold gain and stability ya dots za quantum idahagije. Byongeye kandi, bitewe no kutagira amahame amwe yo guhuza imiterere n'imikorere ya dots za quantum, raporo z'imikorere ya dots za quantum zo mu bihugu bitandukanye na laboratwari ziratandukanye cyane, kandi gusubiramo ntabwo ari hejuru, ibyo kandi bibangamira iterambere rya dots za quantum za colloidal zifite imiterere ya high gain.

Kugeza ubu, laser ya quantum dot electropumped ntabwo iraboneka, bigaragaza ko hakiri imbogamizi mu bushakashatsi bw'ibanze bwa fiziki n'ikoranabuhanga ry'ingenzi rya quantum dot.ibikoresho bya laserUduce twa quantum twa Colloidal (QDS) ni ibikoresho bishya bishobora gutunganywa mu buryo bw’umuti, bishobora kwerekezwa ku miterere y’igikoresho cya electroinjection cya diodes organic-emitting light (LEDs). Ariko, ubushakashatsi buherutse bwerekanye ko gusobanura byoroshye bidahagije kugira ngo harebwe electroinjection colloidal quantum dot laser. Ukurikije itandukaniro mu miterere ya elegitoroniki n’uburyo bwo gutunganya hagati y’uduce twa quantum twa colloidal n’ibikoresho by’umwimerere, guteza imbere uburyo bushya bwo gutegura filime y’umuti bukwiriye utudomo twa quantum twa colloidal n’ibikoresho bifite imikorere ya electron n’imyobo ni bwo buryo bwonyine bwo gukora electrolaser iterwa n’utudomo twa quantum. Sisitemu ya quantum ya colloidal imaze igihe kinini iracyari utudomo twa quantum twa cadmium colloidal turimo ibyuma biremereye. Ukurikije kurengera ibidukikije n’ibyago by’ibinyabuzima, ni ikibazo gikomeye guteza imbere ibikoresho bishya bya quantum dot laser bya colloidal birambye.

Mu mirimo iri imbere, ubushakashatsi ku bikoresho bya quantum dot lasers bikozwe mu buryo bw'ikoranabuhanga na quantum dot lasers bikozwe mu buryo bw'amashanyarazi bigomba kujyana kandi bikagira uruhare runini mu bushakashatsi bw'ibanze no mu bikorwa ngiro. Mu ikoreshwa rya quantum dot lasers, ibibazo byinshi bikunze kugaragara bigomba gukemurwa byihutirwa, kandi uburyo bwo guha agaciro imiterere n'imikorere byihariye ya quantum dot colloidal buracyari ngombwa gusuzumwa.
