Iimveliso

Sichaza indlela entsha yokuhlalutya kwe-phase-sensitive fluorescence emission spectra.Le ndlela ivumela isisombululo semixube yamacandelo amathathu kusetyenziswa i-spectra elinganiswe kwi-frequency modulation frequency.I-spectra ye-Phase-sensitive spectra irekhodwa kusetyenziswa i-modulation frequency frequency, kwinani leengile zesigaba somtshini.Akuyimfuneko ukucinezela nayiphi na inxalenye enye.I-spectra ke isetyenziselwa ukuqikelela ixesha lobomi becandelo kunye ne-steady-state fractional intensity kusetyenziswa inkqubo yohlalutyo olungenamda oluncinci lwesikwere.Imfuno kuphela yohlalutyo lulwazi lwe-specta-state spectra yamacandelo ngamanye.Le nkqubo ivumele isisombululo somxube wamacandelo amabini we-9-methylanthracene (4.5 ns) kunye ne-9,10-diphenylanhracene (5.9 ns).Kufuneka kuqatshelwe ukuba ukusonjululwa kwamaxesha amabini obomi ahluke kuphela ngama-30% ngumsebenzi onzima.Ukongezelela, sisombulule umxube wamacandelo amathathu kunye nexesha lokuphila elihluke kane: p-bis [2- (5-phenyloxazolyl)] ben zene (1.3 ns), 9-methylanthracene (4.5 ns), kunye ne-9,10-diphenylanthracene (5.9) ns).Ngokufanelekileyo, ubuchule busebenzisa i-fluorometer yesigaba esisisigxina esifumanekayo sorhwebo.
