METHOD FOR PATTERNING OF HEMISPHERICAL PHOTONIC CRYSTALLINES AND FABRICATION OF PHOTONIC CRYSTALS WITH VARIOUS SHAPES USING PHOTOCURABLE COLLOIDAL SUSPENSIONS

摘要

Disclosed are a method for patterning of hemispherical photonic crystals and fabrication of photonic crystals with various shapes using photocurable colloidal suspensions. More particularly, the present invention discloses a method for patterning of hemispherical photonic crystals by using a photocurable monomer solution containing high concentration colloidal particles to form a uniform pattern on a lipophilic surface of a substrate with high contact angle to liquid droplets, and then, curing the patterned surface to produce a pattern of the hemispherical photonic crystals, and a method for fabrication of photonic crystals with various shapes by introducing a colloidal solution into a frame having various forms such as microfine tubes. The photonic crystals fabricated using colloidal suspensions may be effectively used in a number of applications including, for example, pixels of a reflective display.
