Book Description
Almost fifteen years have now elapsed since the first observations of per sistent spectral hole-burning in inhomogeneously broadened absorption lines in solids. The fact that the spectral shape of an inhomogeneously broadened line can be locally modified for long periods of time has led to a large number of investigations of low-temperature photophysics and photochemistry that would not have been possible otherwise. Using hole burning, important information has been obtained about a variety of in teractions, including excited-state dephasing processes, host-guest dynam ics, proton tunnelling, low-frequency excitation in amorphous hosts, relaxation mechanisms for vibrational modes, photochemical mechanisms at liquid helium temperatures, and external field perturbations. At the same time, the possibility that persistent spectral holes might be used to store digital information has led to the study of materials and configura tions for frequency-domain optical storage and related possible applica tions. This is the first full-length book on persistent spectral hole-burning. The goal is to provide a broadly based survey of the scientific principles and applications of persistent spectral hole-burning. Since the topic is quite interdisciplinary, the book is intended for researchers, graduate stu dents, and advanced undergraduates in the fields of chemical physics, solid-state physics, laser spectroscopy, solid-state photochemistry, and high-performance optical storage and optical processing.

Book Description
This book describes the underlying scientific fundamentals and principal phenomena associated with persistent spectral hole-burning in solids, and presents an overview of possible future applications to optical storage of digital data and optical signal processing. Organization of the material is by the general physical mechanism responsible for the formation of persistent spectral holes. After a description of the basic principles and methods of hole-burning, with examples from photochemical processes in crystalline and amorphous hosts, the unusual proton tunneling phenomena that occur in hydrogen-bonded polymers and glasses are described. Persistent spectral hole-burning in inorganic materials due either to photoionization or to photophysical effects is then summarized, followed by a detailed discussion of nonphotochemical hole-burning mechanisms for electronic transitions in amorphous solids. The book concludes with a description of potential applications to data storage and optical processsing using frequency-domain, holographic, and electric field techniques. Readers of this volume will gain a detailed appreciation of both the generality of the persistent spectral hole-burning phenomenon and the power of the technique in studying microscopic dynamics and mechanisms of phototransformation in low-temperature solids.

Book Description
Since Dr. Disiich of Germany prepared a glass lens by the sol-gel method around 1970, sol-gel science and technology has continued to develop. Since then this field has seen remarkable technical developments as well as a broadening of the applications of sol-gel science and technology. There is a growing need for a comprehensive reference that treats both the fundamentals and the applications, and this is the aim of "Handbook of Sol-Gel Science and Technology."The primary purpose of sol-gel science and technology is to produce materials, active and non-active including optical, electronic, chemical, sensor, bio- and structural materials. This means that sol-gel science and technology is related to all kinds of manufacturing industries. Thus Volume 1, "Sol-Gel Processing," is devoted to general aspects of processing. Newly developed materials such as organic-inorganic hybrids, photonic crystals, ferroelectric coatings, photocatalysts will be covered. Topics in this volume include: Volume 2, "Characterization of Sol-Gel Materials and Products, "highlights the important fact that useful materials are only produced when characterization is tied to processing. Furthermore, characterization is essential to the understanding of nanostructured materials, and sol-gel technology is a most important technology in this new field. Since nanomaterials display their functional property based on their nano- and micro-structure, "characterization" is very important. Topics found in Volume 2 include: Sol-gel technology is a versatile technology, making it possible to produce a wide variety of materials and to provide existing substances with novel properties. This technology was applied to producingnovel materials, for example organic-inorganic hybrids, which are quite difficult to make by other fabricating techniques, and it was also applied to producing materials based on high temperature superconducting oxides. "Applications of Sol-Gel Technology," (Volume 3), will cover applications such as:

Book Description
In view of the rapid growth in both experimental and theoretical studies of multiphoton processes and multiphoton spectroscopy of atoms, ions and molecules in chemistry, physics, biology, material sciences, etc., it is desirable to publish an Advanced Series that contains review papers readable not only by active researchers in these areas, but also by those who are not experts in the field but who intend to enter the field. The present series attempts to serve this purpose. Each review article is written in a self-contained manner by the experts in the area so that the readers can grasp the knowledge in the area without too much preparation. The topics covered in this volume include OC Ultrafast Photochemical Dynamics in Solution Studied by Femtosecond Time-Resolved Fluorescence Spectroscopy: Involvement of Highly Excited StatesOCO, OC Spectral Selective Studies of Molecular Doped Solids and ApplicationsOCO, OC From Multiphoton to Tunnel IonizationOCO, OC Cluster Dynamics in Intense Laser FieldsOCO, and OC Molecular Theory of Sum-Frequency Generation and its Application to Study Molecular ChiralityOCO. It is hoped that the collection of topics in this volume will be useful not only to active researchers but also to other scientists in biology, chemistry, materials science and physics. This book has been selected for coverage in: . OCo CC / Physical, Chemical & Earth Sciences. OCo Index to Scientific Book Contents- (ISBC). Contents: Ultrafast Photochemical Dynamics in Solution Studied by Femtosecond Time-Resolved Fluorescence Spectroscopy: Involvement of Highly Excited States (T Tahara); Spectral Selective Studies of Molecular Doped Solids and Applications (J-P Galaup); From Multiphoton to Tunnel Ionization (S L Chin); Cluster Dynamics in Intense Laser Fields (D Mathur); Molecular Theory of Sum-frequency Generations and Its Applications to Study Molecular Chirality (M Hayashi & S H Lin).

Book Description
Disordered materials offer new and unexpected insights into the structure of solids and the ways charge carriers move and interact with their environment. The first part of this review volume presents new results and ideas in the subject dealing with the local bonding structure in amorphous and vitreous semiconductors. These include the local bonding structure in chalcogenide glasses containing metal atoms, the interaction of local vibrational modes with their local bonding environment, and new models for the H-bonding configurations.The second part is devoted to questions of low temperature hopping transport and recombination of photocarriers in disordered semiconductors as a function of frequency and at high electric fields. The reviews by leading experts offer different insights and attempt to address problems from the various angles.

Book Description
The research on condensed molecular solids is truly interdisciplinary, spanning the range from statistical and molecular physics to solid-state-physics, chemistry, up to materials science. This Symposium on dynamical processes in condensed molecular systems highlights the most recent developments in the field, focussing on low-dimensional and non-crystalline materials, such as Langmuir-Blodgett-films, polymers and glasses. The text includes both advanced experimental techniques (hole-burning, fluorescence, short-time pulses, nonlinear spectroscopy) and also modern theoretical approches (dynamical percolation, fractals, localization).
