Three-dimensional photonic bandgap crystals of titania hollow spheres at visible wavelengths

---

Abstract
A non-close-packed three-dimensional photonic crystal of titania hollow spheres has been fabricated. The
fabricated process is based on the silica template technique, thermal sintering, and the sol–gel process. The bandstructure calculations and optical measurements both indicate that a quasi-full three-dimensional photonic bandgap located at the visible wavelength has been presented between the eighth and ninth bands. This indicates that the non-close-packed structure of titania hollow spheres was easier to open the complete photonic bandgaps than other face-centered cubic structures made by self-assembling methods at the visible region.
