Available in PDF, EPUB and Kindle. Book excerpt: Optical spectroscopy has been instrumental in the discovery of many lanthanide elements. In return, these elements have always played a prominent role in lighting devices and light conversion technologies (Auer mantles, incandescent lamps, lasers, cathode-ray and plasma displays). They are also presently used in highly sensitive luminescent bio-analyses and cell imaging. This volume of the Handbook on the Physics and Chemistry of Rare Earths is entirely devoted to the photophysical properties of these elements. It is dedicated to the late Professor William T (Bill) Carnall who has pioneered the understanding of lanthanide spectra in the 1960’s and starts with a Dedication to this scientist. The following five chapters describe various aspects of lanthanide spectroscopy and its applications. Chapters 231 presents state-of-the-art theoretical calculations of lanthanide energy levels and transition intensities. It is followed by a review (Chapter 232) on both theoretical and experimental aspects of f-d transitions, a less well known field of lanthanide spectroscopy, yet very important for the design of new optical materials. Chapter 233 describes how confinement effects act on the photophysical properties of lanthanides when they are inserted into nanomaterials, including nanoparticles, nanosheets, nanowires, nanotubes, insulating and semiconductor nanocrystals. The use of lanthanide chelates for biomedical analyses is presented in Chapter 234; long lifetimes of the excited states of lanthanide ions allow the use of time-resolved spectroscopy, which leads to highly sensitive analyses devoid of background effect from the autofluorescence of the samples. The last review (Chapter 235) provides a comprehensive survey of near-infrared (NIR) emitting molecular probes and devices, spanning an all range of compounds, from simple chelates to macrocyclic complexes, heterometallic functional edifices, coordination polymers and other extended structures. Applications ranging from telecommunications to light-emitting diodes and biomedical analyses are assessed. - Provides a comprehensive look at optical spectroscopy and its applications- A volume in the continuing authoritative series which deals with the chemistry, materials science, physics and technology of the rare earth elements

Download or read book Tables for Emission Spectrographic Analysis of Rare Earth Elements written by Ch. Kerekes and published by Elsevier. This book was released on 2013-10-22 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlas and Tables for Emission Spectrographic Analysis of Rare Earth Elements focuses on the analysis of rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion. The book first offers information on the division of the spectra of rare earth elements and Sc and Y into three groups. The spectra of Ce, Pr, Nd, Gd, Tb, Dy, Ho, and Er have lines that, however, do not form characteristic line groups. The text underscores that in preparing the Atlas, the spectral pure-grade rare earth oxides sold by the Johnson & Matthey Co. were considered. Through the help of their spectra, the usable analysis lines and the wavelength values of the interfering spectral lines are created. The operating and photographic conditions are tabulated. The book stresses that for each rare earth, the analysis lines are provided in order of decreasing wavelength. The number located in the lower left corner for each analysis line indicates its relative intensity. The fifteen columns contain the interfering lines of other rare earths and of Sc and Y. The interfering lines are created through the use of the double projector of the Optica Milano Co. and the Gatterer Spectrum. The text is a great source of information for readers wanting to analyze rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion.

Vaseashta and published by Springer Science & Business Media. This book was released on 2007-04-29 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal aim of this NATO Advanced Study Institute (ASI) "Nanostructured and Advanced Materials for Applications in Sensor, Optoelectronic and Photovoltaic Technology" was to present a contemporary overview of the field of nanostructured and advanced electronic materials. Nanotechnology is an emerging scientific field receiving significant worldwide attention. On a nanometer scale, materials or structures may possess new and unique physical properties. Some of these are now known to the scientific community, but there may well be many properties not yet known to us, rendering it as a fascinating area of research and a suitable subject for a NATO ASI. Yet another aspect of the field is the possibility for creating meta-stable phases with unconventional properties and the ultra-miniaturization of current devices, sensors, and machines. Such nanotechnological and related advanced materials have an extremely wide range of potential applications, viz. nanoscale electronics, sensors, optoelectronics, photonics, nano-biological systems, na- medicine, energy storage systems, etc. This is a wide-ranging subject area and therefore requires the formation of multi-disciplinary teams of physicists, chemists, materials scientists, engineers, molecular biologists, pharmacologists, and others to work together on the synthesis and processing of materials and structures, the understanding of their physical properties, the design and fabrication of devices, etc. Hence, in formulating our ASI, we adopted an int- disciplinary approach, bringing together recognised experts in the various fields while retaining a level of treatment accessible to those active in specific individual areas of research and development.

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.

Book excerpt: Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) has been widely adopted as a routine analytical technique for elemental analysis in both industry and academia. However, spectral interference can be a major problem, particularly with such line-rich elements as the rare earth elements. An Atlas of High Resolution Spectra of Rare Earth Elements, which comes complete with a CD of spectra in full colour, is a reference source suitable for all analytical spectroscopists. Using some previously unpublished high resolution spectra, this atlas enables users of ICP-AES to select the best lines of any single rare earth element matrix. Clear instructions for the use of the accompanying CD are provided, which allows all adjacent interferent spectral profiles to be displayed and superimposed. Up-to-date and informative, this unique book will be welcomed as a practical and indispensable reference guide by all those who use ICP-AES for the analysis of rare earth elements.

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 209 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 Rare Earths and Actinides in High Energy Spectroscopy written by Christiane Bonnelle and published by Springer. This book was released on 2015-12-22 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique monograph covers recent theoretical and experimental results on the complex character of f electrons in materials containing lanthanides (rare earths) or actinides, such as alpha-cerium and delta-plutonium. It answers the urgent need for a general presentation of the body of experimental and theoretical results presently available in this challenging domain. Some of the fast developing applications of lanthanide and actinide materials are mentioned. Materials containing atoms with an open f shell have electronic and crystalline properties that are controlled by the localized or delocalized character of the f electrons. This book gives a theoretical discussion of the various spectroscopic methods that shed light on the character of the f electrons and on the connection between their localization and the properties of these materials. Part 1 covers the characteristics of the f electrons in atoms and solids and includes a discussion of the properties of lanthanides and actinides in connection with the f electrons. Part 2 describes the various spectroscopic methods that are used to establish the electronic distributions and energies of the states. Examples involve the determination of f electron distributions by high energy spectroscopy methods with separate treatment of the valence and core electrons. Part 3 concentrates on the theoretical treatment of electronic transitions involving f electrons and simulations of the lanthanide spectra, including comparison with the available experimental data. Part 4 discusses the localized or delocalized character of the f electrons in actinides and their compounds, including comparison (analogies & differences) between the 4f and 5f electron materials. This monograph should be of great value for researchers, academics and engineers working in the fields of high energy spectroscopy, electronic and nuclear science and technology, as well as materials involving rare earths and radio-elements.
