METHOD FOR FABRICATING FILM SHAPED FINE PARTICLE STRUCTURE, AND FILM SHAPED FINE PARTICLE STRUCTURE FABRICATED WITH METHOD, AND OPTICAL ELEMENT USING FILM SHAPED FINE PARTICLE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for fabricating a film shaped fine particle structure which can form a fine particle structure having a face-centered cubic structure other than a [111] orientation, by controlling a direction and a plane direction of the fine particle structure even when the number of particle layers corresponding to the film thickness is several or more.;SOLUTION: The method comprises steps: to fabricate two sheets of single crystal (Si) substrates 801 of which the surfaces have been subjected to etch pit treatment; to fill a micro-space 808 interposed between the two sheets of single crystal substrates 801 fabricated in parallel to each other with a dispersion 803 of spherical monodisperse fine particles; and to form the fine particle structure 807 composed of a colloidal crystal in which the fine particles in the dispersion 803 of the spherical monodisperse fine particles are periodically aligned. Furthermore, the method includes steps: to evaporate (806) the dispersion medium from the fine particle structure 807 composed of the colloidal crystal; and to form the fine particle structure 807 composed of an opal crystal.;COPYRIGHT: (C)2007,JPO&INPIT
