Nano pob zeb diamond Nitrogen vacancy (NV) yog lub teeb-emitting point defect qauv.Nws muaj cov khoom siv kho qhov muag zoo heev thiab cov yam ntxwv ntawm spin polarization.Vim hais tias ntawm nws cov cab kuj tshwj xeeb ruaj khov thiab chav tsev kub atmospheric ib puag ncig compatibility, nws yuav siv tau raws li kub sensor ntawm lom hlwb, thiab kuj yuav siv tau rau qhov tseeb ntsuas ntawm microwave magnetic teb.

Nano pob zeb diamond siv nyob rau hauv super rhiab heev biosensing yog siv nws cov khoom fluorescence.Qhov thib ib yog Raman tus yam ntxwv ncov nyob ntawm 1332 cm-1, thiab qhov thib ob yog qhov tsis muaj nitrogen uas muaj nyob hauv nws, uas yog 637 nm liab fluorescence tawm los ntawm NV.

Ntawm lawv, qhov sib txawv ntawm electron spin quantum xeev ntawm cov nqi tsis zoo NV tuaj yeem tawm fluorescence ntawm qhov sib txawv ntawm qhov ci, thaum nws cov electron spin quantum xeev tau yooj yim cuam tshuam los ntawm qhov tsis muaj zog sib nqus, qhov chaw thermoelectric nyob ib puag ncig thiab pom los ntawm kev hloov fluorescence.Los ntawm laser thiab microwave tswj pib, nws tuaj yeem yooj yim siv cov fluorescence hloov ntawm NV rau super rhiab heev.

Qhov no ultra-sensitive quantum diagnostic platform yog tsim rau ntau hom kev kuaj mob thiab cov kab mob, thiab muaj peev xwm los hloov cov kab mob thaum ntxov rau cov txiaj ntsig ntawm cov neeg mob thiab cov pej xeem.
