| Abstract: | The energy trasfer process of I3MK-RE(Ⅲ)(I3MK=1-acetoacetyl-3-methylindole)complex system in alcohol solution at 77K was analysed with the static properties such as fluorescence and phosphorescence spectra.The rate constant and the efficiency of main energy trasfer process were calculated from fluorescence lifetime,phosphorescence lifetime,quantum yield and time-resolved spectra of I3MK and I3MK-Tb(Ⅲ)stsyem.Accordingly,the dynamics of the energy-transfer process in this system was analysed.A modification of the perrin formula was proposed and the mechanism of the energy transfer of the complex system was disscussed. |
