Abstract

300 nm Eu(DBM)₃ Phen/SiO₂ Colloidal hybrid sphere were synthesized by modified Stöber method. The silica spheres were self-assembled into 3D ordered crystal structure with 5 mm thick and over relative large areas (12 cm²) via sedimentation. The scanning electron microscopy (SEM) images indicate that the cubic-close-packed structure extends almost all of the layers along the direction perpendicular to the surface of the bottom of the beaker and the close-packed order extends throughout the colloidal crystal. Furthermore, elemental analysis of silica spheres by EDAX establishes that the fluorescent molecules contained in the SiO₂ colloidal spheres. Under 355 nm continuous excitation, the ordered structure exhibits characteristic emission of trivalent europium ions.
