Book Description
Photochromism is simply defined as the light induced reversible change of colour. The field has developed rapidly during the past decade as a result of attempts to improve the established materials and to discover new devices for applications.As photochromism bridges molecular, supramolecular and solid state chemistry, as well as organic, inorganic and physical chemistry, such a treatment requires a multidisciplinary approach and a broad presentation. The first edition (1990) provided an enormous amount of new concepts and data, such as the presentation of main families based on the pericyclic reaction mechanism, the review of new families, some bimolecular photocycloadditions and some promising systems. This new edition provides an efficient entry into this flourishing field, with the core content retained from the original work to provide a basic introduction into the different subjects. *Second edition of a work first published in 1990, now revised due to constant development of research. *Including updated lists of references (1989-2001), offering immediate access to recent developments.*Providing great basic interest and high application potential bringing scientists together from chemistry, physics and engineering.

Book Description
Photochromism is the reversible phototransformation of a chemical species between two forms having different absorption spectra. During the phototransformation not only the absorption spectra but also various physicochemical properties change, such as the refractive index, dielectric constant, oxidation/reduction potential, and geometrical structure. The property changes can be applied to photonic equipment such as erasable memory media, photo-optical switch components, and display devices. This book compiles the accomplishments of the research project titled “New Frontiers in Photochromism” supported by the Ministry of Education, Culture, Sports, Science and Technology of Japan. The project focused not only on the above-mentioned classical subjects in photochromism, such as color changes, optical memory, and optical switches, but also on fundamental physicochemical studies and unprecedented application fields that have not yet been explored in photochromism. The latter topics include light-driven mechanical motion, photocontrol of surface wettability, metal deposition on solid materials, photocontrol of chiral properties, ultrafast decoloration dyes, and femtosecond laser experiments, among others.

Book Description
Summarizing all the latest trends and recent topics in one handy volume, this book covers everything needed for a solid understanding of photochromic materials. Following a general introduction to organic photochromic materials, the authors move on to discuss not only the underlying theory but also the properties of such materials. After a selection of pplications, they look at the latest achievements in traditional solution-phase applications, including photochromic-based molecular logic operations and memory, optically modulated supramolecular system and sensors, as well as light-tunable chemical reactions. The book then describes the hotspot areas of photo-switchable surfaces and nanomaterials, photochromic-based luminescence/electronic devices and bulk materials together with light-regulated biological and bio-chemical systems. The authors conclude with a focus on current industrial applications and the future outlook for these materials. Written with both senior researchers and entrants to the field in mind.

Book Description
Thin Films for Optical Coating emphasizes the applications of thin films, deposition of thin films, and thin film characterization. Unlike monographs on this subject, this book presents the views of many expert authors. Individual chapters span a wide arc of topics within this field of study. The book offers an introduction to usual and unusual applications of optical thin films, treating in a more qualitative way general topics such as anticounterfeiting coatings, decorative coatings, light switches, contrast enhancement coatings, multiplexers, optical memories, and more. Contributors review thin film media for optical data storage, UV broadband and narrow-band filters, and optically active thin film coatings. Ion beam sputtering and magnetron sputtering deposition methods are described in detail. Characterization techniques are provided, including Raman spectroscopy and absorption measurements. The book also offers theories on light scattering of thin dielectric films and the electromagnetic properties of nanocermet thin films. This reference incorporates recent research by the individual authors with their views of current developments in their respective fields. Of particular interest to the reader will be an assessment of the historical developments of thin film physics written by one of the fathers of thin film technology, Professor M. Auwärter.
