Available in PDF, EPUB and Kindle. Book excerpt: SERS was discovered in the 1970s and has since grown enormously in breadth, depth, and understanding. One of the major characteristics of SERS is its interdisciplinary nature: it lies at the boundary between physics, chemistry, colloid science, plasmonics, nanotechnology, and biology. By their very nature, it is impossible to find a textbook that will summarize the principles needed for SERS of these rather dissimilar and disconnected topics. Although a basic understanding of these topics is necessary for research projects in SERS with all its many aspects and applications, they are seldom touched upon as a coherent unit during most undergraduate studies in physics or chemistry. This book intends to fill this existing gap in the literature. It provides an overview of the underlying principles of SERS, from the fundamental understanding of the effect to its potential applications. It is aimed primarily at newcomers to the field, graduate students, researchers or scientists, attracted by the many applications of SERS and plasmonics or its basic science. The emphasis is on concepts and background material for SERS, such as Raman spectroscopy, the physics of plasmons, or colloid science, all of them introduced within the context of SERS, and from where the more specialized literature can be followed. Represents one of very few books fully dedicated to the topic of surface-enhanced Raman spectroscopy (SERS) Gives a comprehensive summary of the underlying physical concepts around SERS Provides a detailed analysis of plasmons and plasmonics

Available in PDF, EPUB and Kindle. Book excerpt: This book gives a wide overview of the state-of-the-art applications of Raman spectroscopy in characterization of materials and biomaterials. The Raman signal is intrinsically smaller than other vibrational techniques; however, mainly through intensification processes, such as resonance Raman (RR) and surface-enhanced Raman spectroscopy (SERS), the Raman cross section can be strongly amplified. Thoroughly in these signal amplifications, the study of a diversity of chemical systems and the use of Raman technique for in situ and in vivo measurements is possible. The main goal of this book is to open up to an extended audience the possibilities of uses of Raman spectroscopy. In fact, this collective work will be beneficial to students, teachers, and researchers of many areas who are interested to expand their knowledge about Raman spectroscopy applied to nanotechnology, biotechnology, environmental science, inorganic chemistry, and health sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Raman spectroscopy is one of the fundamental techniques in chemical characterization. It measures the amount of photons and their frequency shifts scattered by the molecule under a given laser beam. The frequency shifts originate from the molecule's vibrations, which are determined by its microscopic structure. Thus, a Raman spectrum is often regarded as the molecule's "fingerprint". When the molecule is placed on a noble metal surface with some curvature, the Raman signals are greatly enhanced by the plasmonic near field at the surface. This technique is called "surface- enhanced Raman spectroscopy", or SERS. Because of the significantly improved sensitivity relative to regular Raman scattering, SERS has grown into a widely popular tool for chemical research and practical applications. Moreover, the molecule-metal interaction that lies in the center of the mechanism of SERS has been a hot topic of fundamental research since its discovery and has led to many variants in the development of spectroscopic techniques. Tip-enhanced Raman spectroscopy (TERS) integrates the scanning probe microscopy and SERS. Similar to SERS, the enhancement of Raman scattering in TERS benefits from the inhomogeneous near field induced by the plasmonic resonance of the noble metal nanostructure. However, the TERS spectrum of a molecule is often found different than SERS, and it changes with the tip position. The combination of the chemical sensitivity and the spatial resolution makes TERS a promising technique for microscopic characterization. A comprehensive demonstration of these unique features is TERS imaging. A TERS image is a two-dimensional map of the Raman intensity at a certain frequency varying with the scanning tip. It exhibits a sub-nanometer resolution and is specific to the corresponding vibrational mode. TERS imaging is considered as a visualization of molecular vibrations and sets stage for a new way of understanding molecules. Therefore, it is necessary to develop theoretical interpretation of TERS images and their connections to the underlying molecular vibration. However, interpreting TERS images is challenging as the brightspot pattern does not always strictly align with the vibrating atoms and the signals are very sensitive to experimental conditions. In this dissertation, three major aspects of TERS theory are explored: the effect of the plasmonic near field electromagnetic mechanism), the plasmonic resonance inside a subnanometer cavity (gap plasmonics), and the quantum mechanical interactions between the molecule and the substrate (the chemical mechanism). In particular, the critical conditions of the near field to achieve atomic resolution are found. It is also illustrated that the locally integrated Raman polarizability density is the sub-molecular property probed by the confined near field in TERS. It provides an intuitive description of the TERS imaging mechanism, which is usually hidden in the self-consistent cycles of conventional calculations using the time-dependent density functional theory. The distinct feature of TERS is largely ascribed to the unique plasmonic properties of a sub-nanometer junction consisting of a flat metal substrate and an atomically sharp tip. At this length scale, atomistic electrodynamics is adopted to describe the nanostructure because it captures the microscopic structure and at the same time retains the efficiency of a classical model.To study the charge-transfer plasmon due to quantum tunneling, a Hirshfeld partitioning scheme is developed to distinguish the plasmonic resonances within and across the coupled nanoparticles. Furthermore, this dissertation presents the development of a new theoretical method to better describe the substrate-molecule coupling, namely, exact frozen density embedding. The method to obtain the response properties of a molecule is derived based on the exact frozen density embedding within the framework of time-dependent density functional theory. Finally, a polarizable frozen density embedding method is developed to include the polarization effect due to the presence of a metal nanoparticle. The development of these theoretical tools is potentially applicable to the studies of the electronic structures of a TERS system.

Book excerpt: Raman spectroscopy is a promising technique because it contains abundant vibrational chemical information. However, Raman spectroscopy is restricted by its small scattering cross section, and many techniques have been developed to amplify Raman scattering intensity. In this dissertation, I study two of these techniques, coherent Raman scattering and surface enhanced Raman scattering and discuss their properties. In the first part of my dissertation, I investigate two coherent Raman processes, coherent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS). In CARS project, I mainly focus on the molecular resonance effect on detection sensitivity, and I find the detection sensitivity can be pushed into 10 [micromolar] with the assistance of molecular resonance. Also, I am able to retrieve background-free Raman spectra from nonresonant signals. For SRS, we develop a new SRS system by applying spectral focusing mechanism technique. We examine the feasibility and sensitivity of our SRS system. The SRS spectra of standards obtained from our system is consistent with literature, and the sensitivity of our system can achieve 10 times above shot-noise limit. In second part of this dissertation, I study surface enhanced Raman scattering (SERS) and related plasmonic effects. I synthesize different shapes of nanoparticles, including nanorod, nanodimer structure with gap and pyramids by template method, and study how electric field enhancement effects correlate to SERS by two photon luminescence (TPL). Also, I build an optical system to study optical image, spectra and particle morphology together. I find that SERS intensity distribution is inhomogeneous and closely related to nanoparticle shape and polarization direction. However, TPL and SERS are not completely correlated, and I believe different relaxation pathways of TPL and SERS and coupling of LSPR and local fields at different frequencies cause unclear correlation between them.

Available in PDF, EPUB and Kindle. Book excerpt: Enhanced Raman spectroscopies, such as surface-enhanced Raman spectroscopy (SERS) and tip-enhanced Raman spectroscopy (TERS), are based on the amplification of intrinsically weak Raman signals of a molecule by metallic nanostructures. The main enhancement is attributed to electromagnetic enhancement. Chemical effects, such as formation of a surface complex, or a charge-transfer complex, co-adsorbed anion effect, also add to the enhancement of the signal. Using SERS, it has been difficult to study details of chemical enhancement and polarization effects due to limited optical resolution of the technique and usage of roughened metal surfaces. These obstacles were overcome with the development of the TERS technique. TERS has extended Raman spectroscopy into the nanoscale region. In this chapter, nanoscale insights into surface chemistry that lead to Raman signal enhancement are described. The effect of molecular binding and orientation as well as commonly used in SERS chloride activation of metal surfaces is discussed. Finally, we describe the future prospects of TERS and the challenges that keep us from harnessing the full potential of the technique.
