Abstract Imprint lithography has emerged as a reliable, reproducible, and rapid method for patterning colloidal nanostructures. As promising alternative to top‐down lithographic approaches, the fabrication of nanodevices thus become effective straightforward. In this study, fusion interference (IL) nanosphere imprint on various target substrates ranging from carbon film transmission electron microscope grid inorganic dopable polymer semiconductor is reported. 1D plasmonic photonic crystals...
The control over the synthesis of gold nanoparticles is crucial to ensure optimal optical and processing properties, but complex interdependent on many variables such as reducing agent, capping amount seeds precursor. Machine learning offers prospect giving insight into this multidimensional problem, reason for selecting a certain model often unclear. Here, we apply tree-based machine algorithms semi-batch, seed-mediated in size range 20–120 nm analyze correlation between parameters,...
Abstract Chains of coupled metallic nanoparticles are special interest for plasmonic applications because they can sustain highly dispersive plasmon bands, allowing strong ballistic wave transport. Whereas early studies focused on homogeneous particle chains exhibiting only one dominant band, heterogeneous assemblies consisting different nanoparticle species came into the spotlight recently. Their increased configuration space principally allows engineering multiple bandgaps, or topological...
In contrast to a macroscopic solid, the color and spectroscopic properties of gold nanoparticles change with size. Here, we propose teaching platform for high school students (hereafter defined as students, attending secondary in Europe, preparatory schools US, or any educational institution comparable level) that explains relationship between perceived colloidal solutions their physicochemical properties. For this aim, an open-source code, based on Mie theory colorimetry, was developed link...
Abstract The formation of well‐defined, functional surfaces that incorporate the unique properties inorganic nanoparticles (NPs) requires robust and scalable fabrication strategies. Herein, we report a methodology for decoration polymer molds with plasmonic (gold) nanoparticle arrays. Wrinkled soft templates were used to assemble gold NPs (74 nm) into line These pre‐formed arrays transferred in subsequent step onto polycarbonate via an injection molding process. Scanning electron microscopy...
Colors generated by plasmonic nanoparticles offer ideal access to nanotechnology for regular consumers, school pupils, or students. Unlike gold as a raw material, change color with size due the unique interaction of metal's free electrons incident light. However, palette solely is limited, thus limiting user experience. Fortunately, using shapes fewer symmetry axes and materials lower damping can help expand palette. Our research explores perception in reflection transmission various types...
Truly spherical silver nanoparticles are of great importance for fundamental studies including plasmonic applications, but the direct synthesis in aqueous media is not feasible. Using commonly employed copper-based etching processes, isotropicplasmonic response can be achieved by well-defined nanocubes. Whilst like shape typically prevailing such we established that there a preferential growth towards rhombicuboctahedra (AgRCOs), which thethermodynamically most stable product this synthesis....
The utilization of plasmonic energy in the form heat, resonance energy, and/or hot carriers offers unique possibilities for various applications, like catalytic and medical due to their simple recyclability or administration. A common strategy make this available direct environment is introduce conductive polymer coatings transfer increase excitons lifetime. However, practical use limited spectral match gold with commonly used polymeric materials semiconductors, oxidation vulnerability...
Localized surface plasmon resonances (LSPRs) have been widely explored in various research fields because of their excellent ability to condense light into a nanometer scale volume. However, it suffers quite often from the broadening LSPR linewidths, resulting low quality factors. Among causes broadening, fabrication inaccuracies are crucial yet challenging evaluate. In this paper, we designed type metal–insulator–metal structure as an example via colloidal self-assembly approach. We then...
