Plasmonic response of complex nanoparticle assemblies

Nano Letters, 2022
Optical properties of nanoparticle assemblies reflect distinctive characteristics of their building blocks and spatial organization, giving rise to emergent phenomena. Integrated experimental and computational studies have established design principles connecting the structure to properties for assembled clusters and superlattices.

Plasmonic Properties of Individual Gallium Nanoparticles

The Journal of Physical Chemistry Letters, 2023
Gallium is a plasmonic material offering ultraviolet to near-infrared tunability, facile and scalable preparation, and good stability of nanoparticles. In our contribution, we experimentally demonstrate the link between the shape and size of individual gallium nanoparticles and their optical properties.

Imaging through plasmonic nanoparticles [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance How is an image transmitted through a material consisting of subwavelength structures? We use two distinct methods to obtain quantitative answers to that question. The first, structural similarity index, is a method related to human perception, initially developed to quantify transmitted image quality following image compression ...

Quantum Dot Thermometry Evaluation of Geometry Dependent Heating Efficiency in Gold Nanoparticles [PDF]

, 2014
Quantum dot based thermometry, in combination with double beam confocal microscopy, was used to investigate the absorption/heating efficiency of gold nanoparticles with different morphologies (nanorods, nanocages, nanoshells, and nanostars), all of them ...

Plasmon-driven synthesis of individual metal@semiconductor core@shell nanoparticles

Nature Communications, 2020
Light-driven heating of plasmonic metal nanoparticles can activate temperature-sensitive reactions at the nanoscale. Here, the authors exploit such nanoscale plasmonic reactors to drive, control, and spectroscopically track the growth of single metal ...

Enhancement of Plasmonic Photovoltaics with Pyramidal Nanoparticles

Applied Optics, 2022
Abstract Light trapping as a result of embedding plasmonic Nano-Particles (NPs) into Photovoltaics (PVs) has been recently used to achieve better optical performance compared to conventional PVs. This light trapping technique enhances the efficiency of PVs by confining the incident light into hot-spot field regions around the NPs, which possess

Single-step assembly of gold nanoparticles into plasmonic colloidosomes at the interface of oleic acid nanodroplets [PDF]

, 2020
Plasmonic gold colloidosomes (Au CSs) of sub-200 nm size are formed by the self-assembly of spherical gold nanoparticles (Au NPs) of ca. 4 nm size at the interface of oleic acid (OA) nanodroplets formed in n-hexane.

Templated green synthesis of plasmonic silver nanoparticles in onion epidermal cells suitable for surface-enhanced Raman and hyper-Raman scattering

Beilstein Journal of Nanotechnology, 2016
We report fast and simple green synthesis of plasmonic silver nanoparticles in the epidermal cells of onions after incubation with AgNO3 solution. The biological environment supports the generation of silver nanostructures in two ways.
