Abstract

The optical diffraction from photonic crystalline colloidal array (CCA) of 119 nm diameter polystyrene colloid diffracting between 500 and 600 nm was examined. The structure of CCA which were determined using Kossel ring analysis and through measurements of the diffraction spot angles was found to be twinned-fcc in all cases. It was attempted to model the diffraction of the CCA using dynamical diffraction theory and using single-particle coherent Mie scattering theory. The stacking fault dependence of the relative diffracted intensities from different crystal planes were also investigated.
