Book Description
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. - Reviews wide range of sol-gel derived coatings including reflective and anti-reflective, self-cleaning, and electrochromic - Discusses latest advances in sol-gel derived photonic crystals including one dimensional, two dimensional, and three dimensional structures - Addresses key applications in solid state lighting, solar cells, sensors, fiber optics, and magneto-optical devices

Book Description
Sol--Gel--Optics encompasses numerous schemes for fabricating optical materials from gels -- materials such as bulk optics, optical waveguides, doped oxides for laser and nonlinear optics, gradient refractive index (GRIN) optics, chemical sensors, environmental sensors, and `smart' windows. Sol--Gel--Optics: Processing and Applications provides in-depth coverage of the synthesis and fabrication of these materials and discusses the optics related to microporous, amorphous, crystalline and composite materials. The reader will also find in this book detailed descriptions of new developments in silica optics, bulk optics, waveguides and thin films. Various applications to sensor and device technology are highlighted. For researchers and students looking for novel optical materials, processing methods or device ideas, Sol--Gel--Optics: Processing and Applications surveys a wide array of promising new avenues for further investigation and for innovative applications. (This book is the first in a new subseries entitled `Electronic Materials: Science and Technology).

Book Description
During my professional career, I developed a strong interest in sol-gel technology, and worked on both xerogel and aerogel systems. My fascination with aerogels has driven me to explore their commercial potential, which is currently an important component of my company's business plan. Together with my co-workers, I have also worked on the preparation of controlled PZT and silica xerogels as well as thin film coatings of metals by the sol-gel technology, These experiences convinced me of the tremendous potentials of this technology. A conviction that is shared by many scientists, engineers, and business leaders around the globe. Many sol-gel derived products are already articles of commerce. However, to expand the commercial potential of sol-gel technology, two challenges must be met: (1) the quality of sol-gel derived products must continue to meet or exceed the quality of competing products, (2) the production cost of sol-gel products (specially aerogels) must continued to decline. A key to lowering the costs of sol-gel products is finding inexpensive precursors.

Book Description
A gradient-index glass rod of about 13 mm in diameter and 20 mm in length with the refractive index difference of about 0.05 between center and perimeter has been prepared by the sol-gel process from a precursor solution consisted of tetramethoxysilane, tetraethoxysilane, boron ethoxide and aqueous solution of lead acetate. A bubble free wet gel of about 35 mm in diameter and 50 mm in length was obtained by adding acetic acid to the precursor solution as a buffering agent. The liquid in the micropores of the wet gel was totally replaced with acetone. Then the compositional gradient of lead was formed in radial direction of the gel by soaking in an ethanolic solution of potassium acetate. A transparent r-GRIN rod of about 13 mm in diameter was obtained by sintering the gel at 550 deg C.

Book Description
Sol-Gel Techniques for Glass Producers and Users provides technological information, descriptions and characterizations of prototypes, or products already on the market, and illustrates advantages and disadvantages of the sol-gel process in comparison to other methods. The first chapter entitled "Wet Chemical Technology" gives a summary of the basic principles of the sol-gel chemistry. The most promising applications are related to coatings. Chapter 2 describes the various "Wet Chemical Coating Technologies" from glass cleaning to many deposition and post-coating treatment techniques. These include patterning of coatings through direct or indirect techniques which have became very important and for which the sol-gel processing is particularly well adapted. Chapter 3 entitled "Bulk Glass Technologies" reports on the preparation of special glasses for different applications. Chapter 4 entitled "Coatings and Materials Properties" describes the properties of the different coatings and the sol-gel materials, fibers and powders. The chapter also includes a section dedicated to the characterization techniques especially applied to sol-gel coatings and products.
