“…In addition to 3D photonic crystals, 2D colloidal monolayers can also be tuned to create many different optical materials and properties. For example, the monolayer can be used for shadow deposition to generate different shapes of deposited materials, 97,120,124,186 used as an etch mask to generate high aspect ratio structures with high order, 166,187,188 inverted/textured to create antireflective coatings for reducing the amount of reflected light from a substrate surface, 95 or deformed to generate structurally colored patterns on a substrate. 112 Interesting coupling effects can be observed between the photonic modes of an opal and the plasmonic modes of thin metals deposited on top of the crystal.…”

[189][190][191][192][193] Colloids can also be used for antireflective coating applications. 85 In particular, colloidal monolayers have been used to create porous, graded-index materials with low reflectivity by, for example, plasma etching of colloidal monolayers, 194 inverting the monolayer, 95 or using the monolayer as an etching mask to generate pillars.…”

Nature evolved a variety of hierarchical structures that produce sophisticated functions. Inspired by these natural materials, colloidal self-assembly provides a convenient way to produce structures from simple building blocks with a variety of complex functions beyond those found in nature. In particular, colloid-based porous materials (CBPM) can be made from a wide variety of materials. The internal structure of CBPM also has several key attributes, namely porosity on a sub-micrometer length scale, interconnectivity of these pores, and a controllable degree of order. The combination of structure and composition allow CBPM to attain properties important for modern applications such as photonic inks, colorimetric sensors, self-cleaning surfaces, water purification systems, or batteries. This review summarizes recent developments in the field of CBPM, including principles for their design, fabrication, and applications, with a particular focus on structural features and materials' properties that enable these applications. We begin with a short introduction to the wide variety of patterns that can be generated by colloidal self-assembly and templating processes. We then discuss different applications of such structures, focusing on optics, wetting, sensing, catalysis, and electrodes. Different fields of applications require different properties, yet the modularity of the assembly process of CBPM provides a high degree of tunability and tailorability in composition and structure. We examine the significance of properties such as structure, composition, and degree of order on the materials' functions and use, as well as trends in and future directions for the development of CBPM.

Here we present measurements on a metasurface composed by tilted gold nanowires. The metasurface can induce an optical chiral response of the whole sample when the light impinges on the sample out of the normal incidence angle. In order to investigate the symmetry breaking induced by the geometry, we measured the second harmonic generation (SHG) signal generated by circular polarized pulsed light. This technique has demonstrated to be a powerful method in order to investigate the chiral morphology of nanostructures.

“…Enhancement of the optical electric field stronger than that due to the LSP alone was reported. Au nanoparticles/nanostructure were used to exhibit the LSP resonance by some studies 4,6 because of the chemical stability of Au. Thus, robustness in applications is expected.…”

“…On the other hand, Ag nanoparticles/nanostructure were employed in some studies 1, 2, 5, 3 because of their high performance of the electric field enhancement. For the photonic crystal material, polystyrene (a regular array of particles or a regular pattern) was selected in some studies, 2,4,3,6 while poly(methyl methacrylate) was used by Xu et al 5 and silica was used by Kim et al 1 An advantage of polystyrene is narrow particle size dispersity. Polystyrene suspensions with the dispersity less than few percent in the coefficient of variation can be synthesized by a soap-free emulsion polymerization.…”

Aiming at fabrication of hybrid plasmonic-photonic crystals, gel-immobilized colloidal crystals made of a polystyrene colloidal suspension and an N -(Hydroxy methyl)acrylamidbased gel were immersed into an aqueous dispersion of gold nanoparticles. Atomic force microscope (AFM) observations have been performed for the gel-immobilized colloidal crystals with gold nanoparticles deposited on their surfaces. In the present study, the diameter of a colloidal sphere was c.a. 190 nm. The diameter of a gold nanoparticle was the same as in a preliminary study, c.a. 40 nm. Various immersion times up to two hours were tested. Surface of a sample of 2 hr immersion has been observed. Prior to the AFM observation, the sample was dried in a desiccator for 18 hrs. We have identified a facecentered cubic {111} structure of a colloidal crystal of nearly close packing. Nanoparticles isolated with one another have been observed on the surface of gel-immobilized crystal, which can be regarded as gold nanoparticles from their sizes.2
