| 摘 要： | In this paper,we have investigated the spectral characteristics of Eu~(3 )ion sorbed on NaY,NaX and NaAzeolites.During calcination,the influence of Eu~(3 )ion's positions in zeolites on its spectral structures are dis-cussed emphatically.The experimental results show that the electric dipole-to-magnetic dipole transition inten-sity ratios of Eu~(3 )emission in NaY,NaX and NaA zeolites calcinated at the same temperature increase inproper order.The bonding actions between Eu~(3 )ion and framework oxygens are studied by the measurementsof excitation spectra and X-ray photoelectron spectroscopy.In the Eu~(3 )content ranging from 0.95% to10.5%,the concentration quenching of the fluorescence in Eu(Ⅲ)-NaY is not observed.
