Download or read book Handbook on the Physics and Chemistry of Rare Earths written by Karl Albert Gschneidner and published by North-Holland. This book was released on 1996 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume covers various physical aspects of a wide range of rare-earth materials. Magnetic phenomena dominate the contents of the first four chapters which deal with thin films and layered structures, and intermetallic and nonmetallic compounds. The remaining two chapters deal with coherent emission and electronic structure calculations of lanthanide molecules.The first chapter covers the state-of-the-art of the synthesis and properties of thin films of the rare-earth metals and layered superstructures of two rare-earth metals. The following chapter is a review of rare-earth-transition metal nanoscale multilayers and describes the recent advances in our understanding of magnetic structure, interfacial magnetism, and origin of perpendicular magnetic anisotropy of lanthanide-transition-metal nanoscale multilayers. The next chapter deals with one of the important series of rare-earth intermetallic compounds, those which possess the ThNm 12 -type structure. The authors of the following chapter review the specific magnetic and magnetoelastic properties of certain crystals, which are determined by the localized electronic magnetic moments of the lanthanide ions in the crystal lattice and their interactions with each other and surrounding ions. The chapter on coherent emission differs from other reviews on the subject in that it concentrates on the broader issues. Here the emphasis is on superradiance, superfluorescence, amplification of spontaneous emission by other stimulated emision than the laser effect and coherent spontaneous emission. The final chapter describes the progress that has been made in electronic structure calculations of lanthanide-containing molecules, especially in the last 10 years.

Book excerpt: Recent studies indicate that China accounts for about 96 percent of the world’s supply of rare earth materials (REMs). With REMs becoming increasingly important for a growing number of high-tech applications, appropriate action must be taken to mitigate the effects of a shortage of critical REMs in defense systems and components. Bringing together information previously available only from disparate journal articles and databases, Rare Earth Materials: Properties and Applications describes the unique characteristics and applications of 17 REMs. It defines their chemical, electrical, thermal, and optical characteristics. Maintaining a focus on physical and chemical properties, it addresses the history and critical issues pertaining to mining and processing of REMs. In this book, Dr. A.R. Jha continues his distinguished track record of distilling complex theoretical physical concepts into an understandable technical framework that can be extended to practical applications across commercial and industrial frameworks. He summarizes the chemical, optical, electrical, thermal, magnetic, and spectroscopic properties of REMs best suited for next-generation commercial and military systems or equipment. Coverage includes extraction, recycling, refinement, visual inspection, identification of spectroscopic parameters, quality control, element separation based on specific application, pricing control, and environmental / geo-political considerations. Potential applications are identified with an emphasis on scientific instruments, nuclear resonance imaging equipment, MRI systems, magnetic couplers for uranium enrichment equipment, battery-electrodes, electric motors, electric generators, underwater sensors, and commercial and military sensors. The book describes unique applications of rare earth magnets in all-electric and hybrid electric cars and microwave components. It also considers the use of rare earth magnets in commercial and military systems where weight and size are the critical design requirements. Suitable for both students and design engineers involved in the development of high-technology components or systems, the book concludes by summarizing future applications in electro-optic systems and components, including infrared lasers, diode-pumped solid-state lasers operating at room temperatures, and other sophisticated military and commercial test equipment

Available in PDF, EPUB and Kindle. Book excerpt: When the author began working on phosphors based on rare-earth elements, he lacked an introductory textbook that explained the fundamental chemistry, basic optical properties, and magnetic characteristics of lanthanide elements. This book provides a concise overview of the rare-earth elements and is divided into two parts. In the first part, the reader receives an overview of solid-state chemistry and fundamental physical properties of these elements. Key topics of the first part include the separation chemistry of lanthanides, their chemical behaviour and physical properties. Then relevant compound classes are illustrated, crystal structures are systematically explained. The second part focuses on the optical and magnetic properties on relevant examples, also discussing many applications. Students and researchers new to the topic of "Rare-Earth Elements" receive a comprehensive introduction to understand basic optical and magnetic properties and incentives for deeper studies.

Available in PDF, EPUB and Kindle. Book excerpt: The 13th Rare Earth Research Conference was held October 16- 19, 1977 in Wilson Lodge at Oglebay Park near Wheeling, West Vir g1n1a. From the small conference held originally at Lake Arrow head, California in 1960 the meetings have grown steadily in size and stature until they are now recognized as the premier conference devoted exclusively to the science and technology of rare earth systems. In keeping with the spirit which has prevailed since the Lake Arrowhead days a number of improvements were instituted on the oc casion of the 13th Conference. For the first time poster sessions were introduced, and they proved to be a splendid success. This was a year of another first - a review system for manuscripts. Dr. McCarthy, who undertood the arduous task of Program Chairman, and Dr. Rhyne, who along with Dr. McCarthy edited the conference proceedings, were mainly responsible for suggesting and implement ing these innovations. The layout at Wilson Lodge was nearly ideal for the conference in that poster and oral sessions were in very close proximity, facilitating the efforts of the attendees to make the most of the conference.
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.

Download or read book Handbook on the Physics and Chemistry of Rare Earths written by and published by Elsevier. This book was released on 2011-09-22 with total page 559 pages. 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
