Photonic crystals, which are the artificial multidimensional periodic structures, are attractive for ultra-compact optoelectronic devices. One of the simple methods is using self-assembly nanospheres such as polystyrene or silica beads to form 3D Close-Packed crystalline structures. An important issue for colloidal spheres based photonic bandgap (PBG) devices is how to fabricate the devices with small bandgap-shift for optoelectronic device applications. In general, it is difficult to tune the size of colloidal spheres continuously excepting for controlling the strict synthesis conditions. In this paper, we demonstrate a simple method that can control the bandgap position by utilizing hybrid polymer and silica beads with large size-difference.
