| Abstract: | Visible luminescent macroporous materials covalently bonded with europium and terbium complexes were prepared using polystyrene spheres (PS) as the template. Both of the obtained terbium(Ш) macroporous material (Tb(Ш)-M) and europium(Ш) macroporous material (Eu(Ш)-M) exhibit close-packed spherical porous structure according to the SEM images. Furthermore, their BET surface areas were determined by the N2 adsorption-desorption isotherms. The two samples show corresponding characteristic green and red luminescence, respectively. Moreover, IR spectra and photoluminescence (PL) properties suggest that the Tb/Eu(Ш) ions were coordinated with organic group grafted on macroporous matrix. The luminescent lifetimes were also measured. |
