colloidal hybrid spheres 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 cm
2
) via sedimentation.The scanning electronmicros copy (SEM) images indicate that the cubic-close-packed structure extends almostall of the layers along the direction perpendicular to the surface of the bottom of the beakerand 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 SiO
