Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, novel graphene related materials (GRMs), perovskites, as well as metal oxides and other metal nanostructures have received the interest of the scientific community. Due to their extraordinary physical, optical, thermal, and electrical properties, which are correlated with their 2D ultrathin atomic layer structure, large interlayer distance, ease of functionalization, and bandgap tunability, these nanomaterials have been applied in the development or the improvement of innovative optoelectronic applications, as well as the expansion of theoretical studies and simulations in the fast-growing fields of energy (photovoltaics, energy storage, fuel cells, hydrogen storage, catalysis, etc.), electronics, photonics, spintronics, and sensing devices. The continuous nanostructure-based applications development has provided the ability to significantly improve existing products and to explore the design of materials and devices with novel functionalities. This book demonstrates some of the most recent trends and advances in the interdisciplinary field of optoelectronics. Most articles focus on light emitting diodes (LEDs) and solar cells (SCs), including organic, inorganic, and hybrid configurations, whereas the rest address photodetectors, transistors, and other well-known dynamic optoelectronic devices. In this context, this exceptional collection of articles is directed at a broad scientific audience of chemists, materials scientists, physicists, and engineers, with the goals of highlighting the potential of innovative optoelectronic applications incorporating nanostructures and inspiring their realization.

Book excerpt: This thesis aims to explore the possibilities and limitations of employing metal nanoparticles for photovoltaic solar energy conversion. Plasmon-induced charge separation and energy transfer phenomena are explored in three experimental systems. In the first, 13 nm gold and 25 nm silver nanoparticles located at a TiO2/hole conductor interface are found to generate sustainable photocurrents upon excitation of the particles' localized surface plasmon resonance. The photocurrent response closely follows the plasmonic absorption characteristics of the nanoparticles. A simple and fast method for the fabrication of these plasmonic solar cells is developed, based on electrostatic metal nanoparticle self-assembly. The method allows for the controlled creation of optically homogenous and dense nanoparticle monolayers with well-defined interparticle separations. The absorbed photon-to-electron conversion efficiency is found to significantly increase with deceasing particle size to a maximum of 15% for 5 nm Au nanoparticles, while it is found to be largely independent of the nanoparticle density. Three mechanisms for surface plasmon resonance based charge carrier separation are proposed and discussed. Self-assembly strategies based on molecular linkers are explored to enable a closer control over the nanoscale engineering of the TiO2/NP and NP/hole transport material interfaces. These strategies are also used to fabricate plasmonic solar cells based on anisotropic metal nanoparticles and self-assembled plasmonic nanostructures.In the second experimental system, the energy transfer between organic molecules and gold nanoparticles is studied in a colloidal model system. This energy transfer potentially enables the use of metal nanoparticles as 'light harvesting antennas' in photovoltaic devices. The distance and wavelength dependence of the electronic coupling between fluorophores and gold nanoparticles is determined theoretically and experimentally via steady state and time- resolved fluorescence spectroscopy. The fluorescence quenching of 4 different dye molecules, which absorb light at different wavelengths across the visible spectrum and into the near- infrared, is studied using a rigid silica shell as a spacer. A comprehensive experimental determination of the distance dependence from complete quenching to no coupling is carried out by a systematic variation of the silica shell thickness. Electrodynamic theory predicts the observed quenching quantitatively in terms of energy transfer from the molecular emitter to the gold nanoparticle. The plasmonic field enhancement in the vicinity of the 13 nm gold nanoparticle is calculated as a function of distance and excitation wavelength and is included in all calculations. Relative radiative and energy transfer rates are determined experimentally and are in good agreement with calculated rates. In control experiments, dye-dye interactions are found to have a severe effect on the fluorescence properties of dyes attached to the surface of a silica nanoparticle. This allows us to determine the experimental conditions, under which dye-dye interactions do not affect the experimental results.The energy transfer between gold nanoparticles and sensitizers in a dye-sensitized solar cell is explored in the third system and preliminary results are presented. The incorporation of gold nanoparticles in different dye-sensitized solar cell architectures is found to result in a decrease of the generated photocurrent in all cases. Different strategies for the incorporation of gold nanoparticles into dye-sensitized solar cells are evaluated and the importance of reference devices to evaluate the influence of the nanoparticle incorporation is highlighted.
Download or read book Nanoplasmonics written by Grégory Barbillon and published by BoD – Books on Demand. This book was released on 2017-06-21 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoplasmonics is a young topic of research, which is part of nanophotonics and nano-optics. Nanoplasmonics concerns to the investigation of electron oscillations in metallic nanostructures and nanoparticles. Surface plasmons have optical properties, which are very interesting. For instance, surface plasmons have the unique capacity to confine light at the nanoscale. Moreover, surface plasmons are very sensitive to the surrounding medium and the properties of the materials on which they propagate. In addition to the above, the surface plasmon resonances can be controlled by adjusting the size, shape, periodicity, and materials' nature. All these optical properties can enable a great number of applications, such as biosensors, optical modulators, photodetectors, and photovoltaic devices. This book is intended for a broad audience and provides an overview of some of the fundamental knowledges and applications of nanoplasmonics.

Download or read book Nanoscale Electrochemistry written by Andrew J. Wain and published by Elsevier. This book was released on 2021-09-14 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoscale Electrochemistry focuses on challenges and advances in electrochemical nanoscience at solid–liquid interfaces, highlighting the most prominent developments of the last decade. Nanotechnology has had a tremendous effect on the multidisciplinary field of electrochemistry, yielding new fundamental insights that have broadened our understanding of interfacial processes and stimulating new and diverse applications. The book begins with a tutorial chapter to introduce the principles of nanoscale electrochemical systems and emphasize their unique behavior compared with their macro/microscopic counterparts. Building on this, the following three chapters present analytical applications, such as sensing and electrochemical imaging, that are familiar to the traditional electrochemist but whose extension to the nanoscale is nontrivial and reveals new chemical information. The subsequent three chapters present exciting new electrochemical methodologies that are specific to the nanoscale, including "single entity"-based methods and surface-enhanced electrochemical spectroscopy. These techniques, now sufficiently mature for exposition, have paved the way for major developments in our understanding of solid–liquid interfaces and continue to push electrochemical analysis toward atomic-length scales. The final three chapters address the rich overlap between electrochemistry and nanomaterials science, highlighting notable applications in energy conversion and storage. This is an important reference for both academic and industrial researchers who are seeking to learn more about how nanoscale electrochemistry has developed in recent years. Outlines the major applications of nanoscale electrochemistry in energy storage, spectroscopy and biology Summarizes the major principles of nanoscale electrochemical systems, exploring how they differ from similar system types Discusses the major challenges of electrochemical analysis at the nanoscale
