Download or read book Spectroscopy of Crystals Containing Rare Earth Ions written by A.A. Kaplyanskii and published by Elsevier. This book was released on 2012-12-02 with total page 767 pages. Available in PDF, EPUB and Kindle. Book excerpt: ``Spectroscopy of Crystals Containing Rare Earth Ions'' contains chapters on some key problems selected from a broad range of spectroscopic studies of RE-activated solids including both crystalline and glassy materials. Progress in crystal field theory is surveyed, an area which is basic to our understanding of the energy levels. The treatment of dynamical properties includes studies of coherence phenomena in isolated ions, energy transfer between ions and co-operative phenomena associated with ion-ion and ion-lattice interactions. In addition, the role of electron spins and nuclear spins is studied by light scattering and double resonance techniques. The presence of inhomogeneous broadening of spectral lines is observed and studied in many contexts, leading to new insights into general problems of the disordered state. Considerable attention is devoted to describing new experimental techniques whose development is of prime importance for progress in the spectroscopy of RE-activated solids. Many of these rely on the development and application of tunable lasers. At the moment this is a very active field of spectroscopy with more exciting developments likely to occur in the future.

Download or read book Theoretical Spectroscopy of Transition Metal and Rare Earth Ions written by Mikhail G. Brik and published by CRC Press. This book was released on 2019-12-11 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes in detail the main concepts of theoretical spectroscopy of transition metal and rare-earth ions. It shows how the energy levels of different electron configurations are formed and calculated for the ions in a free state and in crystals, how group theory can help in solving main spectroscopic problems, and how the modern DFT-based methods of calculations of electronic structure can be combined with the semi-empirical crystal field models. The style of presentation makes the book helpful for a wide audience ranging from graduate students to experienced researchers. Performance of optical materials crucially depends on the impurity ions intentionally introduced into the crystalline host materials. The color of these materials, their emission and absorption spectra can be understood by analyzing the relations between the electronic properties of impurity ions and host crystal structure, which constitutes the main content of this book. It describes in detail the main concepts of theoretical spectroscopy of transition metal and rare earth ions.

Download or read book Photoacoustic and Photothermal Spectroscopy written by Surya N. Thakur and published by Elsevier. This book was released on 2022-12-07 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photoacoustic and Photothermal Spectroscopy: Principles and Applications introduces the basic principles, instrumentation and major developments in the many applications of Photoacoustic and Photothermal Spectroscopy over the last three decades. The book explains the processes of sound generation by periodic optical excitation and ultrasonic generation by pulsed laser excitation and describes the workings of photoacoustic cells equipped with microphones and piezoelectric transducers. Photoacoustic imaging (PAI) is one of the fastest-growing imaging modalities of recent times. It combines the advantages of ultrasound and optical imaging techniques. These non-invasive and non-destructive techniques offer many benefits to users by enabling spectroscopy of opaque and inhomogeneous materials, (solid, liquid, powder, gel, gases) without any sample preparation, and more. - Written in a non-mathematical, simple-to-read manner - Presents recent developments in the field, along with the scope of future progress, including up-to-date references - Includes detailed illustrations, such as equipment layout, spectra, experimental setups, tables, photographs, and more

Available in PDF, EPUB and Kindle. Book excerpt: Handbook on the Physics and Chemistry of Rare Earths: Including Actinides is a continuous series of books covering all aspects of rare earth science, including chemistry, life sciences, materials science, and physics. The book's main emphasis is on rare earth elements [Sc, Y, and the lanthanides (La through Lu], but whenever relevant, information is also included on the closely related actinide elements. Individual chapters are comprehensive, broad, up-to-date, critical reviews written by highly experienced, invited experts. The series, which was started in 1978 by Professor Karl A. Gschneidner Jr., combines, and integrates, both the fundamentals and applications of these elements with two published volumes each year. - Presents up-to-date overviews and new developments in the field of rare earths, covering both their physics and chemistry - Contains Individual chapters that are comprehensive and broad, with critical reviews - Provides contributions from highly experienced, invited experts

Download or read book Binary Fluorides written by Donald T. Hawkins and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coverage For some time, we have contemplated a comprehensive review of the structures and force fields of the binary fluorides. This bibliography of 1498 references marks the first step of that effort. We are pub lishing this material now rather than waiting until the review is complete some two years hence because we believe that the information already accumulated will be of immediate use to a broad spectrum of researchers. Anyone ambitious enough to read through all the articles on binary fluorides will find that the struc tures and force fields of many of these molecules are at present unknown. For example, it has not been clearly established to which point group(s) the lanthanide trifluorides should be assigned. There remain interesting problems relating to the role of Jahn-Teller and pseudo-Jahn-Teller distortions in some of the transition metal fluorides such as VF , MoF , ReF , and ReF , to name only a few. One s s 6 7 also finds fascinating examples of large-amplitude motions, or pseudorotations, as they are often called, in such molecules as XeF 6, I F 7, and PF 5' For those binary fluorides whose equilibrium geometries are precisely known, there still exists the problem of accurately determining the harmonic force field. In a few cases, most notably the Group VA trifluorides, there has been some attempt made at extracting the cubic and quartic contributions to the force field.
