In this study, a kind of much uniform and rule hemispheric ordered porous Eu (TTA)(3)(TPPO)(2)/ZnO composite was synthesized by liquid phase grafting method, and ordered mesoporous ZnO was necessarily used as precursor during preparation process. The diameter of the hemispheric particle was about 1 mu m, and the surfaces of the hemispheric particles were distributed a lot of ordered porous, the pore size was about 2.18 nm. Eu(TTA)(3)(TPPO) 2 was assembled into porous ZnO matrix by liquid phase grafting method. At the same time, the Eu(TTA)(3)(TPPO)(2) guest material played a role of structure-directing agent, which led to a realignment of porous ZnO particle, and a hemispheric morphology was obtained. ZnO had a strong emission peak at 469 nm which overlaps with the F-7(0)-D-5(2) transition excitation peak of Eu3+ at 465 nm, it indicated that the effective energy transfer could be happened between ZnO and Eu3+, which strongly enhanced the luminescence intensity of Eu3+. The optimal ratios of Eu3+ was also discussed. (C) 2019 Elsevier B.V. All rights reserved.
