| 摘 要： | Monodisperse silica spheres of 252 nm with a standard deviation of 5.7% are prepared by Stber method. By compari-son of both of media, ethanol instead of water is used to assemble opal, and the artiflcial opal has been prepared by the sedimentation inethanol of silica spheres. The structure of the opal prepared has been examined and discussed. The results show that the artificial opal hasa structure similar to the face-centered cubic (fcc) type packed system with silica spheres. Transmission measurements of the artificial opalhave been conducted, which shows that the artificial opal is quasi-full band gap silica photonic crystals in the visible region. |

| Abstract: | Monodisperse silica spheres of 252 nm with a standard deviation of 5.7% are prepared by Stober method. By comparison of both of media, ethanol instead of water is used to assemble opal, and the artificial opal has been prepared by the sedimentation in ethanol of silica spheres. The structure of the opal prepared has been examined and discussed. The results show that the artificial opal has a structure similar to the face-centered cubic (fcc) type packed system with silica spheres. Transmission measurements of the artificial opal have been conducted, which shows that the artificial opal is quasi-full band gap silica photonic crystals in the visible region. |
