The ideal metal nanoparticles for SERS must not only fulfill important requirements such as high near-field enhancement and a tunable far-field response but also overcome the diffusion limitation at extremely lower concentrations of a target material. Here, we introduce a novel method to produce gold nanoparticles with open eccentric cavities by selectively adapting the structure of non-plasmonic nanoparticles via acid-mediated surface replacement. Copper oxide nanoparticles with open eccentric cavities are first prepared using a microwave-irradiation-assisted surfactant-free hydrothermal reaction and are then transformed into gold nanoparticles by an acidic gold precursor while maintaining their original structure. Because of the strong near-field enhancement occurring at the mouth of the open cavities and the very rough surfaces resulting from the uniformly covered hyperbranched sharp multi-tips and the free access of SERS molecules inside of the nanoparticles without diffusion limitation, adenine, one of the four bases in DNA, in an extremely diluted aqueous solution (1.0 pM) was successfully detected with excellent reproducibility upon laser excitation with a 785-nm wavelength.

    RSC Advances REVIEW View Article Online View Journal | View Issue Plasmonic nanoparticles in chemical analysis Jan Krajczewski, Karol Koła˛taj and Andrzej Kudelski* Cite this: RSC Adv.,2017,7, 17559 Many very sensitive analytical methods utilising specific properties of plasmonic metal nanoparticles have been developed.

  • University of Trento Parallel FDTD Electromagnetic Simulation of Dispersive Plasmonic Nanostructures and Opal Photonic Crystals in the Optical Frequency Range
    PhD Dissertation International Doctoral School in Information and Communication Technologies DISI - University of Trento Parallel FDTD Electromagnetic Simulation of Dispersive Plasmonic Nanostructures and Opal Photonic Crystals in the Optical Frequency Range Antonino Cal`aLesina Advisor: Dott. Alessandro Vaccari FBK - Fondazione Bruno Kessler REET - Renewable Energies and Environmental Technologies XXV Cycle - April 2013 Abstract In the last decade, nanotechnology has enormously and rapidly developed. The technological progress has allowed the practical realization of devices that in the past have been studied only from a theoretical point of view. In particular we focus here on nanotechnologies for the optical frequency range, such as plasmonic devices and photonic crystals, which are used in many areas of engineering. Plasmonic noble metal nanoparticles are used in order to improve the photovoltaic solar cell efficiency for their for- ward scattering and electromagnetic field enhancement properties. Pho- tonic crystals are used for example in low threshold lasers, biosensors and compact optical waveguide. The numerical simulation of complex problems in the field of plasmonics and photonics is cumbersome. The dispersive behavior has to be modeled in an accurate way in order to have a detailed description of the fields. Besides the code parallelization is needed in order to simulate large and realistic problems. Finite Difference Time Domain (FDTD) is the numerical method used for solving the Maxwell's equations and simulating the electromagnetic interaction between the optical radiation and the nanostructures. A modified algorithm for the Drude dispersion is proposed and validated in the case of noble metal nanoparticles. The modi- fied approach is extended to other dispersion models from a theoretical point of view.

Through simulations, comprehensive comparisons of the electron energy loss spectroscopy (EELS) and the optical performance are discussed for a gold spherical dimer system in terms of different dielectric models. Our study offers a paradigm of high efficiency compatible dielectric theoretical framework for accounting the metallic nanoparticles behavior combining local, nonlocal and size-dependent effects in broader energy and size ranges. The results of accurate analysis and simulation for these effects unveil the weight and the evolution of both surface and bulk plasmons vibrational mechanisms, which are important for further understanding the electrodynamics properties of structures at the nanoscale. Particularly, our method can be extended to other plasmonic nanostructures where quantum-size or strongly interacting effects are likely to play an important role.

Development of wavelength-scale optical elements that are able to efficiently generate, manipulate and detect light, along with their subsequent integration on functional devices and systems, have been one of the main focuses of ongoing research in nanophotonics. To achieve coherent light generation at the nanoscale, much of the research over the last few decades has focused on achieving lasing using high- index dielectric resonators in the form of photonic crystals or whispering gallery mode resonators. More recently, nano-lasers based on metallic resonators that sustain surface plasmons – collective electron oscillations at the interface between a metal and a dielectric – have emerged as a promising candidate. This article discusses the fundamentals of surface plasmons and the various embodiments of plasmonic resonators that serve as the building block for plasmon lasers.

However, they still undergo unoptimized light collection due mainly to the thin (~350 nm) polycrystalline absorber layers. Moreover, their high toxicity (due to the presence of lead in the perovskite crystalline structure) makes it necessary that the thickness of the absorber layers to be further reduced, for their future commercialization, without reducing the device performance. Here we aim to address these issues via embedding spherical plasmonic nanoparticles of various sizes, composition, concentrations, and vertical positions, for the first time in realistic halide-based perovskite solar cells architecture, and to clarify their effect on the absorption properties and enhancement. We theoretically show that plasmon-enhanced near-field effects and scattering leads to a device photocurrent enhancement of up to ~7.3% when silver spheres are embedded inside the perovskite layer.

This article is published with open access at Springerlink.com Abstract. The term ‘plasmon’ was first coined in 1956 to describe collective electronic oscillations in solids which were very similar to electronic oscillations/surface waves in a plasma discharge (effectively the same formulae can be used to describe the frequencies of these physical phenomena). Surface waves originating in a plasma were initially considered to be just a tool for basic research, until they were successfully used for the generation of large-area plasmas for nanoscale materials synthesis and processing. To demonstrate the synergies between ‘plasmons’ and ‘plasmas’, these large-area plasmas can be used to make plasmonic nanostructures which functionally enhance a range of emerging devices. The incorporation of plasma- fabricated metal-based nanostructures into plasmonic devices is the missing link needed to bridge not only surface waves from traditional plasma physics and surface plasmons from optics, but also, more topically, macroscopic gaseous and nanoscale metal plasmas.

  • Metamaterials Based on Plasmonic Nanoshells and Loss-Compensation Using Fluorescent Dye Molecules and Quantum Dots
    Metamaterials based on plasmonic nanoshells and loss-compensation using fluorescent dye molecules and quantum dots Salvatore Campione and Filippo Capolino* Dept. of Electrical Engineering and Computer Science, University of California, Irvine, CA 92697- 2625, USA ABSTRACT Composite materials based on plasmonic nanoparticles allow building metamaterials with very large effective permittivity (positive or negative) or ε-near-zero; moreover, if clustered or combined with other nanoparticles, it is possible to generate also effective magnetic permeability (positive or negative), and an ad-hoc design would result in the generation of double negative materials, and therefore backward wave propagation. However, losses are usually significant and affect the metamaterial performance. In this work, we report on the possibility of adopting fluorescent dye molecules or quantum dots, optically pumped, embedded into the dielectric cores of the employed nanoshell particles, and provide loss-compensation in ordered 3D periodic arrays at optical frequencies. Each spherical nanoshell is modeled as an electric dipole. We consider nanoparticles with gold and silver shells. We then find the modes with complex wavenumber in the metamaterial, and describe the composite material in terms of homogenized effective material parameters (refractive index and permittivity). Furthermore, in case of loss-compensation, we compare the results obtained from modal analysis with the ones computed by using two different homogenization methods: (i) Maxwell Garnett homogenization theory and (ii) Nicholson-Ross-Weir retrieval method. We show the design of two ε- near-zero metamaterials with low losses by simulating gain material made of dyes or quantum dots with realistic parameters. A brief discussion about the employment of the two kinds of active gain materials adopted here is given in the end.
