SURFACE PLASMON RESONANCE OF ABSORPTION AT DENSELY PACKED PLASMONIC NANOCOMPOSITES

Physics, Chemistry and Applications of Nanostructures, 2013
For planar nanocomposites Ag-LiF fabricated by the thermal vacuum evaporation and characterized by a high volume part of a metal phase (p = 0.6-0.8), the concentration features of the surface plasmon absorption band were analyzed. Based on the probabilistic approach to the description of a nanocomposite structure, the new combined model of the ...

Colloidal Plasmonic Nanocomposites: From Fabrication to Optical Function

Chemical Reviews, 2018
Plasmonic nanostructures are extensively used building blocks for engineering optical materials and device architectures. Plasmonic nanocomposites (pNCs) are an emerging class of materials that integrate these nanostructures into hierarchical and often multifunctional systems.

Plasmonic Hybrid Nanocomposites for Plasmon-Enhanced Fluorescence and Their Biomedical Applications

2020
Fluorescence is a powerful tool in biochemistry, biophysics, forensic science, and biotechnology. Two main principal properties for any fluorophore, brightness and photostability, are fundamentally important to achieve a high level of sensitivity for detection.

Plasmon mediated super-absorber flexible nanocomposites for metamaterials

Nanoscale, 2013
A flexible host has been selected to achieve, for the first time, functional nanocomposites based on CdSe@ZnS core-shell type quantum dots (QDs) and Au nanoparticles (NPs), simultaneously dispersed in a polymer matrix. Coherent interactions between QDs and plasmonic Au NPs embedded in PDMS films have been demonstrated to lead to a relevant enhancement ...

Poling‐Assisted Fabrication of Plasmonic Nanocomposite Devices in Glass

Advanced Materials, 2010
We report on the fabrication and optical properties of large-scale plasmonic nanocomposite metamaterial directly within glass matrix by thermal electric-field poling of glass. The achieved structure exhibits an enhanced backscattering (see Figure), which has strong dependence on the exposure of the surface to different organic vapors and can be used ...

Plasmonic Coupling in Silver Nanocomposite Glasses

The Journal of Physical Chemistry C, 2012
This work demonstrates that an enhanced plasmonic response can be attained and tuned for Ag nanocomposite glasses via a real-time in situ control of the plasmonic coupling between closely spaced Ag nanoparticles (NPs). The result is achieved by a two-step modification of Ag NP-doped glasses.

Deposition of plasmon gold–fluoropolymer nanocomposites

Physics Letters A, 2016
Abstract Degradation-resistant two-dimensional metal–fluoropolymer composites consisting of gold nanoparticles coated with a thin fluoropolymer film were deposited on a substrate by hot wire chemical vapour deposition (HWCVD) and ion sputtering. The morphology and optical properties of the obtained coatings were determined.

An Omnidirectional Transparent Conducting‐Metal‐Based Plasmonic Nanocomposite

Advanced Materials, 2011
A transparent conducting metal (TCM) composed of a stack of a gold film and silver/polymer nanocomposite fabricated by sputtering onto a glass substrate is presented. The plasmonic metamaterial shows an omnidirectional optical transmission up to 80 in the visible spectrum, which is comparable to that of ITO, and the electrical conductivity is one order
