1. Mehloli ea khanya ea Fluorescence le ea lihlopha tse ngata
Ha lielektrone tsa extranuclear li thabile ’me li qhomela boemong ba thabo, lielektrone tse boemong ba thabo ha lia tsitsa ’me li lula li qhomela ho khutlela fatše ka matla a tlaase.Nakong ea ho qhoma, matla a amohelehang a tla lokolloa ka mokhoa oa photons..Ketsahalo ea hore ntho e thabela boemo ba thabo ka mor'a ho khantšitsoe ke photon ea wavelength e itseng, ebe e khutlela boemong bo tlaase ba matla ka ho lokolla photon ea bolelele bo bong bo itseng.
E bitsoa phenomenon ea photoluminescence, 'me nako ea bophelo ea photon hangata e lokolloa e ka tlase ho metsotsoana ea 0.000001, e bitsoang fluorescence;pakeng tsa 0.0001 le 0.1 motsotsoana, e bitsoa phosphorescence.Haeba ntho e ka itlhahisa le ho hlahisa fluorescence ntle le ho tsosoa ha leseli la kantle, ho boleloa hore ntho e na le fluorescence ea kahare.Boemo bo bong ba fluorescence ke ho hlahisa maqhubu a khanya a nang le maqhubu a fapaneng a maqhubu ho tloha ho maqhubu a leseli a pele (hangata ke maqhubu a khutsufalitsoeng a maqhubu a makhutšoane ho hlahisa maqhubu a malelele) tlas'a ts'usumetso ea mohloli oa leseli o kantle, 'me ponahatso ea macroscopic ke ho ntša leseli le leng la mebala.Mohloli oa lebone la li-multi-band ha o fane feela ka mohloli oa leseli o fapaneng bakeng sa ho shebella intrinsic fluorescence, empa hape le mohloli o khanyang oa khanya.
