Document Type and Number:
Japanese Patent JP7186384
Kind Code:
B2
Abstract:
A colloidal crystal structure (10) includes a colloidal crystal layer (3) including a plurality of colloidal particles (1) and a binder (2) disposed between the plurality of colloidal particles to fix the colloidal particles, and a refractive index control material that is provided on one surface of the colloidal structural layer, is transparent, and has a refractive index difference of less than 10% with respect to the binder. A light-emitting device includes an optical filter (32) including the colloidal crystal structure, and a light source, and a part of primary light emitted by the light source passes through the optical filter. A lighting system includes the light-emitting device.
