Method for patterning of hemispherical photonic crystallines and fabrication of photonic crystals with various shapes using photocurable colloidal suspensions

摘要

PURPOSE: A method for patterning of hemispherical photonic crystals using a colloidal dispersing agent and a manufacturing method of photonic crystals are provided to produce a large amount of the photonic crystals conveniently. CONSTITUTION: A method for manufacturing colloidal photonic crystals includes a step for injecting colloidal particles of 150~100,000nm size contained in a monomer solution to a UV curing macromolecular solution, and a step for forming colloidal photonic crystals by irradiating UV on a dispersing medium introduced to a mold frame. A manufacturing method of porous photonic crystal includes the following steps of: injecting a colloidal particle of 150~100,000nm size dispersed in a UV curing macromolecular solution to the mold frame; forming colloidal photonic crystal by irradiating UV to the dispersing medium; and removing colloid from the colloidal photonic crystal selectively.
