A so-called inside-outside double modification path is used to functionalize zeolite A (ZA) with two kinds of luminescent lanthanide species (Eu3+/Tb3+ complex of thenoyltrifluoroacetylacetone (TAA) and acetylacetone (AA), and lanthanide polyoxometalate (NaLnW10O36?2H2O (LnW10, Ln-?Eu, Tb, Dy)) to prepare the multi-component hybrid materials. ZA is functionalized with Eu3+/Tb3+ through ion exchange reaction, and then TTA/AA ligands are introduced through gas dispersion (ship in bottle) method to the inside channel or pore structure of ZA. On the other hand, another species, LnW10, is fabricated onto the surface of ZA through ionic liquid (1-methyl-3-propionyloxy imidazolium bromide) coordinated to titania as linker. The prepared hybrids show the multi-color luminescence for different composition and excitation. The results provide a useful path to obtain multi-component lanthanide hybrids.
