ABSTRACT:A novel fabrication of hierarchically ordered organic and inorganic hybrid structures at length scales ranging from nanometers to micrometers was demonstrated by oxygen plasma treatment of self-organized silicon-containing block copolymer films. The rod-coil type silicon-containing block copolymer, polystyrene-b-polyisoprene with polyhedral oligomeric silsesquioxane (POSS) -modified side chains, was successfully synthesized by hydrosilation of polystyrene-b-poly(1,2-ran-3,4-isoprene) block copolymer with hydrido-heptacyclopentyl substituted POSS. The films were prepared from the polymer solution by casting on silicon wafers under a moist air flow. The self-organized microstructures were investigated by electron microscopy. It was found that the hexagonally packed micropores and phaseseparated nanodomains were formed within the films. Oxygen plasma etching of the films provided novel hierarchically ordered hybrid structures.

Abstract-This study fabricated periodic 3D nanostructures by using a periodic voxel array for light extraction. Two-photon polymerization (TPP) is a well-known technology used for generating complex 3D micro-and nanostructures with sub-100-nm resolution. Because of the periodic voxel-by-voxel array fabrication process, the fabrication of holographic two-photon polymerization (HTPP) can be faster than that of traditional TPP. HTPP promises a flexible technique to fabricate an arbitrary periodic 3D structured optical surface. In this research, we used a 25 × 25 beam-splitting holographic mask to generate a periodic focus in a photocured material and to systematically fabricate complex 3D nanostructures at rates of mm² per minute. The optical responses of nanostructures with a 1 μm period fabricated in a polymer were characterized using 3D optical microscopy. The experimental results of the light distribution demonstrated favorable agreement with those of the simulation. In the light-extracting experiment, the light extraction capability of the gold-layer nanostructures was 3.6 times higher than that of the glass without nanostructures.

Optically active nanostructures comprised of polymer multilayer microspheres surrounding semiconductor quantum dots are studied. Comparative analysis of the optical properties of the microspheres with four alternating layers with different refractive indices is performed. Photoluminescence and extinction characteristics of the microspheres are determined by the dimensions, internal structure, and the average refractive index of the particles.
