Synthesis, characterization, and diffraction study of three-dimensional icosahedral quasicrystals

Abstract Three-dimensional icosahedral quasicrystals have been fabricated by two-photon polymerization technique. Such quasicrystals have icosahedral symmetry in three dimensions which is forbidden for true periodic crystals. The correspondence of the resulting quasicrystals to the designed structures was confirmed by scanning electron microscopy. We investigated the optical interference properties of icosahedral quasicrystals using a laser diffraction technique.
