【Abstract】 The sensitized fluorescence intensity of terbium ion is notably enhanced when the Tb 3+ fleroxacin(FLRX) complex is exposed to 365 nm ultraviolet light. Based on the analysis of the fluorescence spectra, phosphorescence spectra and fluorescence quantum yield and life time of the system, it was proved that irradiation of the Tb 3+ FLRX complex makes it undergo a photochemical reaction and a new terbium complex which is more favorable to intramolecular energy transfer is formed. The mechanism of the photochemical fluorescence enhancement is discussed.更多还原
