  • Fine particle structure and optical medium
    Patent number: 7063890
    Abstract: Such a structure is to be provided in that in the case where a material, such as a protective film, is coated on a fine particle accumulated layer, such as a photonic crystal, penetration of the material into gaps among the fine particles is suppressed, whereby the mechanical strength against bending stress and tensile stress is improved, and peeling and breakage of the fine particle accumulated layer are suppressed, without adverse affect on the optical characteristics, such as reflection characteristics.
