Imikhiqizo

Sichaza indlela entsha yokuhlaziywa kwe-spectra ephumayo ye-fluorescence ezwelayo.Le ndlela ivumela ukuxazululwa kwezingxube zezingxenye ezintathu kusetshenziswa i-spectra elinganiswa ngemvamisa eyodwa yokushintshashintsha.Izibukeli ezizwelayo esigabeni zirekhodwa kusetshenziswa ifrikhwensi eyodwa yokushintshashintsha, enanini lama-engeli esigaba somtshina.Akudingekile ukucindezela noma iyiphi ingxenye eyodwa.I-spectra ibe isetshenziselwa ukulinganisa isikhathi sokuphila sengxenye namandla e-fractional eqinile kusetshenziswa inqubo yokuhlaziya izikwele ezincane ezingaqondile.Okuwukuphela kwesidingo sokuhlaziya ulwazi lwe-spectra yesimo esingashintshi sezingxenye ngazinye.Le nqubo ivumele ukuxazululwa kwengxube yezingxenye ezimbili ze-9-methylanthracene (4.5 ns) kanye ne-9,10-diphenylanthracene (5.9 ns).Kufanele kuqashelwe ukuthi ukuxazulula izikhathi ezimbili zokuphila ezihluke ngama-30% kuphela kuwumsebenzi onzima.Ukwengeza, sixazulule inhlanganisela yezingxenye ezintathu nezikhathi zokuphila ezihluke ngokuphindwe kane: i-p-bis[2-(5-phenyloxazolyl)] ben zene (1.3 ns), 9-methylanthracene (4.5 ns), kanye ne-9,10-diphenylanthracene (5.9) ns).Kalula, le ndlela isebenzisa i-fluorometer yesigaba se-fixed-frequency etholakalayo ethengiswayo.
