Research Abstract

Pyramidal assemblies of polystyrene (PS) or SiO2 particles were fabricated by micromolding underneath top-gathering pillar arrays, and their optical properties were investigated. The transmittance and reflectance spectra of the assemblies composed of PS particles showed a dip and a peak, which corresponded to a Bragg reflection.
