Available in PDF, EPUB and Kindle. Book excerpt: A method was developed to access the interior of light-guiding structures in order to exploit the enhanced sensing potential of the highly confined electromagnetic field distributions, located within the core of a waveguide. The work presented in this thesis explores therefore the possibilities of optical waveguide spectroscopy utilising transparent mesoporous thin-film waveguides deposited on top of athin gold layer. These multi-layer assemblies are employed in a prism-coupling attenuated total internal reflection (ATR) configuration. The angular read-out of the reflected light intensity allows label-free detection schemes with high sensitivity to changes of the dielectric environment in the case of the presence of analyte molecules within the probing region. This optical waveguide spectroscopy technique has been used to study the real-timediffusion of Ruthenium 535-bisTBA (N-719) dye into mesoporous nanocrystalline titaniumdioxide films. The porous films were prepared on top of gold substrates and prism coupling was used to create a guided wave in the nanocrystalline film. Dying was carried out by bring the film into contact with a 3 x 10-4 moldm-3 dye solution and using optical waveguide spectroscopy to monitor the change in both the refractive index and theextinction coefficient of the nanoporous layer as dye diffused into the porous network. Dyeuptake in a 1.27?m film was slow with the refractive index of the film still increasing after 22 hours.

Download or read book Sol Gel Derived Optical and Photonic Materials written by Rui Almeida and published by Woodhead Publishing. This book was released on 2020-11-25 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sol-gel processing is a low temperature, low cost wet chemistry route to a range of different materials, particularly glassy and ceramic oxides, including nanoparticles and powders, fibers, thin films and membranes, or monoliths and composites. Thin films and coatings represent by far the most important category of sol-gel derived products with optical, electronic and magnetic functionalities, for example photoresist and dielectric spin-on-glass layers, flat screen displays, anti-reflection, conducting and magnetic disk coatings, as well as photochromic, electrochromic and photovoltaic coatings. Sol-gel derived materials are homogeneous at the molecular level and are a good example of a bottom-up approach to materials synthesis. There is increasing need of new optical and photonic materials with improved performance, where molecular level homogeneity and easy fabrication in film form may be especially convenient, highlighting a decisive advantage of sol-gel over other more established technologies to obtain graded index optical components, solar control coatings, phosphors, glass ceramics or multilayer photonic structures. There is no book available yet which focuses in particular on optical and photonic sol-gel derived materials. This is what makes this book unique at this point for those especially or exclusively interested in optical and photonic functional materials and applications. This book represents an important tool to update scientists and engineers with recent advances in the rapidly evolving field of optical and photonic materials, components and devices. Our target audience are those working in materials science, physics, engineering and chemistry disciplines, in particular academics and researchers working in advanced optical/photonic processing technologies, research and development engineers in high technology industries and research project leaders. This book will also be an essential tool for graduate students pursuing a PhD or even a Master’s degree.

The evaluation of nanomaterials in the form of different shapes, sizes, and volumes needed for utilization in different kinds of gadgets and devices. Since the recently developed two-dimensional carbon materials are proving to be immensely important for new configurations in the miniature scale in the modern technology, it is imperative to innovate various atomic and molecular arrangements for the modifications of structural properties. Of late, graphene and graphene-related derivatives have been proven as the most versatile two-dimensional nanomaterials with superb mechanical, electrical, electronic, optical, and magnetic properties. To understand the in-depth technology, an effort has been made to explain the basics of nano dimensional materials. The importance of nano particles in various aspects of nano technology is clearly indicated. There is more than one chapter describing the use of nanomaterials as sensors. In this volume, an effort has been made to clarify the use of such materials from non-conductor to highly conducting species. It is expected that this book will be useful to the postgraduate and research students as this is a multidisciplinary subject.
