While the chemistry, physics, and optical properties of simple atoms and molecules are quite well understood, this book demonstrates that there is much to be learned about the optics of nanomaterials. Through comparative analysis of the size-dependent optical response from nanomaterials, it is shown that although strides have been made in computational chemistry and physics, bridging length scales from nano to macro remains a major challenge. Organic, molecular, polymer, and biological systems are shown to be potentially useful models for assembly. Our progress in understanding the optical properties of biological nanomaterials is important driving force for a variety of applications.

This book introduces the fascinating world of plasmonics and physics at the nanoscale, with a focus on simulations and the theoretical aspects of optics and nanotechnology. A research field with numerous applications, plasmonics bridges the gap between the micrometer length scale of light and the secrets of the nanoworld. This is achieved by binding light to charge density oscillations of metallic nanostructures, so-called surface plasmons, which allow electromagnetic radiation to be focussed down to spots as small as a few nanometers. The book is a snapshot of recent and ongoing research and at the same time outlines our present understanding of the optical properties of metallic nanoparticles, ranging from the tunability of plasmonic resonances to the ultrafast dynamics of light-matter interaction. Beginning with a gentle introduction that highlights the basics of plasmonic interactions and plasmon imaging, the author then presents a suitable theoretical framework for the description of metallic nanostructures. This model based on this framework is first solved analytically for simple systems, and subsequently through numerical simulations for more general cases where, for example, surface roughness, nonlinear and nonlocal effects or metamaterials are investigated.

This book presents studies of complex nanostructures with unique optical responses from both theoretical and experimental perspectives. The theory approaches the optical response of a complex structure from both quantum-mechanical and semiclassical frameworks, and is used to understand experimental results at a fundamental level as well as to form a quantitative model to allow the design of custom nanostructures. The experiments utilize scanning transmission electron microscopy and its associated analytical spectroscopies to observe nanoscale optical effects, such as surface plasmon resonances, with nanometer-scale spatial resolution. Furthermore, there is a focus in the dissertation on the combination of distinct techniques to study the difficult-to-access aspects of the nanoscale response of complex nanostructures: the combination of complementary spectroscopies, the combination of electron microscopy and photonics, and the combination of experiment and theory. Overall, the work demonstrates the importance of observing nanoscale optical phenomena in complex structures, and observing them directly at the nanoscale.

Plasmonic nanostructures are of great interest due to the broad range of applications from biodetection to metamaterial. The desired optical functionality of these nanostructures can only be realized if the designed geometries and constituent material quality are accurately reproduced experimentally. This dissertation research developed new fabrication methods to create planar and freestanding plasmonic nanostructures, including two-dimensional (2D) planar gold (Au) nanoparticle quasicrystals, one-dimensional (1D) Au nanoparticle arrays, and ring-loaded Au nanoparticle dimer nanoantennas. The measured and modeled optical properties of each type of structure were found to be in strong agreement with one another, thereby confirming the effectiveness of the fabrication approaches in reproducing the designed structure. In Chapter 2, planar 2D plasmonic quasicrystal arrays composed of spherical Au nanoparticles were created by Au-enhanced oxidation of lithographically patterned stacks of evaporated amorphous silicon (a-Si) and Au thin films. In contrast to 2D periodic plasmonic structures, which can be accurately simulated for arbitrarily shaped nanoparticles, computationally efficient models for quasicrystals require spherical particle geometries. Using the process developed in this research, broadband Ammann-Beenker and multiband Penrose plasmonic quasicrystals were fabricated and optically characterized. The measured transmission spectra of the fabricated structures agreed well with simulation, thereby enabling an experimental validation of the modeled interaction between the plasmonic and photonic modes of the two structures. In Chapter 3, freestanding 1D Au nanoparticle arrays encapsulated within a silicon dioxide (SiO2) shell were produced by Au-enhanced oxidation of Au-coated, surface modulated Si nanowires. This lithography-free process overcomes the linear relationship between nanoparticle diameter and interparticle spacing imposed by the Rayleigh instability, and provides accurate and reproducible control of both of these parameters over a wide range of particle diameters and spacings. The modeled optical properties of fabricated 1D arrays were confirmed experimentally by extinction measurements of a randomly oriented ensemble of wires as well as by scanning transmission electron microscopy (STEM) electron energy loss spectra (EELS) and energy filtered transmission electron microscopy (EFTEM) analysis of individual wire arrays. In Chapter 4, a nanoring-loaded dimer nanoantenna was designed to give a multiband optical plasmonic response. The center wavelength and bandwidth of the two bands was varied by modifying the nanoring inner diameter. A top-down process was optimized to reproducibly fabricate the ring-loaded nanoantenna with sub-10 nm wide gaps between the three particles and an inner/outer nanoring diameter of 30nm and 55nm, respectively. Electromagnetic modeling showed that the multi-band response originated from differences in coupling between the nanoring and nanoparticle building blocks for the long- and short-wavelength resonances. The optical response was also understood by modeling the electric/magnetic field and charge distribution of the nanoantennas at the two resonant wavelengths.

Optical properties are among the most fascinating and useful properties of nanomaterials and have been extensively studied using a variety of optical spectroscopic techniques. A basic understanding of the optical properties and related spectroscopic techniques is essential for anyone who is interested in learning about nanomaterials of semiconductors, insulators or metal. This is partly because optical properties are intimately related to other properties and functionalities (e.g. electronic, magnetic, and thermal) that are of fundamental importance to many technological applications, such as energy conversion, chemical analysis, biomedicine, optoelectronics, communication, and radiation detection.Intentionally designed for upper-level undergraduate students and beginning graduate students with some basic knowledge of quantum mechanics, this book provides the first systematic coverage of optical properties and spectroscopic techniques of nanomaterials.
