Inzwa yobushushu bokukhanya kweFayibha, Inkqubo yokubeka iliso ekrelekrele, Kusasazwe umenzi ifayibha optic e China
Umgaqo weFluorescence Lifetime Temperature Measurement
Emva kokukhanyiswa ngokukhanya, ii-electron ezikwimathiriyeli enovakalelo zifunxa iifotoni kunye notshintsho ukusuka kwinqanaba elisezantsi lamandla ukuya kwinqanaba eliphezulu lamandla elichulumancisayo, kwaye emva koko ubuyele kumgangatho ophantsi wamandla ngotshintsho lwemitha, ukukhutshwa kwe-fluorescence. Ukukhutshwa kwe-fluorescence okuzinzileyo emva kokuba isibane esivuselelayo sisusiwe kuxhomekeke kubomi bemeko echulumancisayo.. Le mveliso idla ngokubola ngokukhawuleza, kunye nexesha elingatshintshiyo lokubola kwe-exponential lingasetyenziselwa ukulinganisa ubomi bemeko echulumancisayo, ebizwa ngokuba lixesha lokubola kwe-fluorescence okanye ixesha lokubola kwe-fluorescence.
Isivamvo seqondo lobushushu bobomi be-Fluorescence
Ubude bobomi be-fluorescence buxhomekeke kubushushu. I-Fluorescence ye-fluorescence yeqondo lobushushu ebomini ikhupha i-spectra ehambelanayo kwi-spectrum ebonakalayo emva kokuba izinto ezithile ezinqabileyo zomhlaba ezine-fluorescent zikhanyiselwe kwaye zivuyiswe kukukhanya kwe-ultraviolet., yiyo i, i-fluorescence kunye ne-afterglow yayo yi-luminescence emva kokuyeka ukuvuselela. Ukuba iparameter ye-fluorescence iguqulwa yiqondo lokushisa kunye nobudlelwane be-monotonic, olu budlelwane lunokusetyenziselwa ukulinganisa ubushushu. Ubunzulu bembonakalo yomgca bunxulumene nobunzulu bomthombo wokukhanya wovuselelo kunye nobushushu bemathiriyeli yefluorescent.. Ukuba umthombo wokukhanya uhlala uhleli, Ubunzulu bespectrum yefluorescent linear lixabiso elinye lomsebenzi wobushushu kunye nokubola ngokuhamba kwexesha.. Ngokubanzi, Ubushushu bangaphandle busezantsi, kokukhona i-fluorescence yomelele kwaye icotha ukubola kwe-afterglow. Ngokuhluza i-spectrum yovuselelo ngesihluzo kunye nokulinganisa ubunzulu bemigca ye-fluorescence afterglow emission spectral., ubushushu bunokumiselwa. Kodwa le ndlela yokulinganisa idinga ukuqina kokukhanya okuzinzileyo kunye nejelo lomqondiso, ekunzima ukuyifezekisa, ngoko ayifane isetyenziswe. Ukwengeza, ixesha lokubola okungaguquguqukiyo kwe-fluorescence afterglow ikwangumsebenzi wexabiso elinye lobushushu.
Ukusuka kwimbono yethiyori ye-semiconductor, ukubola kunye nokunyamalala kokukhazimla yinkqubo yokucima ukukhanya. Ukuphakama kobushushu, kokukhona intshukumo yomelele, kokukhona iiphonon zithatha inxaxheba ekufunxeni, kwaye ngokukhawuleza ukukhanya kucima. Ngoko ke, ubushushu bezinto ze-fluorescent bumisela isantya sokucima ukukhanya, yiyo i, ubungakanani bexesha lokubola rhoqo.
Olona ncedo lukhulu lokusebenzisa ubomi be-fluorescence kumlinganiselo wobushushu kukuba ubudlelwane boguqulo lobushushu bumiselwa bubomi be-fluorescence., kwaye ayichatshazelwa zezinye izinto zangaphandle ezifana notshintsho kwi-excitation light source source, Ukuhanjiswa kwefayibha ngokufanelekileyo, okanye idigri yokudibanisa. Ngoko ke, inoncedo olubalulekileyo ngaphezulu kwendlela yokulinganisa ubushushu usebenzisa i-fluorescence peak intensity okanye intensity ratio njengophawu lwemvakalelo yobushushu., kwaye isekwe kumgaqo womlinganiselo wobushushu befiber optic.
