英文摘要	Containerless solidification processing was introduced for the first time to fabricate 3D photonic crystal. Micrometer-sized amorphous BaTi2O5 spheres with perfect spherical shape and superior optical properties such as high refractive index (n=2.15) were produced via containerless solidification processing. 3D opal photonic crystal was assembled with these spheres by spaced-confined method using a box of precisely controlled size. Plane-wave method was implemented to calculate band structures and analyze influence of refractive index on band-gaps. The obtained results show that this 3D opal structure has incomplete band-gap, and band-gap narrows and moves toward lower frequency with the increase of refractive index along the [111] direction. The results demonstrate that the containerless solidification processing provides an approach to fabricate superior metastable spherical materials which can be used to form 3D opal photonic crystals.
