Plasmonic Nanocomposite Layers on Glass and Silicon

2010
A novel method to fabricate in situ Au nanoparticles in solid matrix thin films of TiO2 and SiO2 and their absorption and reflectance properties are described. This method is based in a sol-gel process combined with a spin-coating procedure. The thin films are deposited on glass or Si (100) plates in order to measure the absorption and reflectance ...

Broad-band plasmonic absorbing nanocomposites

Journal of Optical Technology, 2014
This paper discusses the spectrally selective properties of Ag-Na3AlF6 multilayer plasmonic nanocomposites formed on glass, quartz, and polymer substrates during thermal evaporation in vacuum. It is demonstrated that they can be used as a basis for creating broad-band optical coatings characterized by strong absorption of electromagnetic radiation in ...

Optical attenuation of plasmonic nanocomposites within photonic devices

Applied Optics, 2013
Plasmonic nanostructures enable microscopic optical manipulation such as light trapping in photonic devices. However, integration of embedded nanostructures into photonic devices has been limited by tractability of nanoscale and microscale descriptions in device architectures.

Toxicity of Plasmonic Nanomaterials and Their Hybrid Nanocomposites

2014
Abstract Nanomaterials are defined as particles, fibers and tubes, composite materials, and nanostructured surfaces with at least one dimension smaller than 100 nm (i.e., 10− 9 m). Over the last decades, interest for engineered nanomaterials with specific physicochemical properties has grown dramatically. This opens great opportunities for use and is

Local-field effects in magneto-plasmonic nanocomposites

Journal of the Optical Society of America B, 2010
A self-consistent analytical approach was developed to describe the optical properties of an assembly of magneto-plasmonic composite nanoparticles distributed on a dielectric substrate. The proposed theory is based on the effective susceptibility concept in the frame of Green’s function method and accounts for the local-field effects in the system. The

Au based Nanocomposites Towards Plasmonic Applications

AIP Conference Proceedings, 2010
Incorporation of nano‐sized metals in polymers can transfer their unique features to the host matrix, providing nanocomposite materials with improved optical, electric, magnetic and mechanical properties. In this work, colloidal Au nanorods have been incorporated into PMMA based random co‐polymer, properly functionalized with amino groups and the ...

Synthesis and characterization of Cu-C60 plasmonic nanocomposite

Physica B: Condensed Matter, 2018
Abstract Plasmonic nanocomposite thin film containing Cu metal nanoparticles in fullerene C60 matrix is developed by thermal co-evaporation method on glass substrate. In order to excite the surface plasmon resonance (SPR), thermal annealing is performed from 100 °C to 400 °C on as-deposited thin film in an inert atmosphere (continuous flow of Ar gas)
