Book Synopsis Optical Spectra of Transparent Rare Earth Compounds by : S. Hufner
Download or read book Optical Spectra of Transparent Rare Earth Compounds written by S. Hufner and published by Elsevier. This book was released on 2012-12-02 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical Spectra of Transparent Rare Earth Compounds investigates the optical spectra of transparent rare earth (RE) compounds such as europium chalcogenides. Emphasis is placed on the underlying physics in selected examples, and theoretical results are usually presented without proof in a form that allows their application to the interpretation of experimental data. This book is comprised of 11 chapters and begins with an overview of the spectra of RE ions in ionic crystals, paying particular attention to the sharpness of many lines in the absorption and emission spectra. How these very narrow lines arise, what interactions determine their energy, and how they can be used to investigate particular properties of the solid state are explained in detail. Subsequent chapters explore the energy structure of RE free ions in solids; trivalent RE ions in a static crystal field and in a phonon field; magnetic interactions and hyperfine interactions; and Jahn-Teller systems. The absorption spectra of europium chalcogenides are also considered, along with REs in glasses and RE lasers. This monograph is written primarily for solid state physicists and those who need an overall view of the basic features of rare earth spectra in transparent solids, such as new workers.
Book Synopsis Theoretical Spectroscopy of Transition Metal and Rare Earth Ions by : Mikhail G. Brik
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.
Book Synopsis Spectroscopy of Crystals Containing Rare Earth Ions by : A.A. Kaplyanskii
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.

Book Synopsis Energy Levels and Predicted Absorption Spectra of Rare-Earth Ions in Rare-Earth Arsenides by :
Download or read book Energy Levels and Predicted Absorption Spectra of Rare-Earth Ions in Rare-Earth Arsenides written by and published by . This book was released on 1992 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: A crystal-field Hamiltonian for octahedral symmetry was used along with free-ion parameters for aqueous solution to fit the reported optical absorption spectra of Er(3+) in ErAs. Predictions showed excellent agreement with reported experimental data at so 74, and 300 K. Consequently, we used an interpolation procedure to predict the crystal-field splittings of the lower multiplets of the rare-earth ions Tb(3+) through Yb(3+) in their respective arsenide compounds. The lowest multiplet energy levels predicted for Tm(3+) and Yb(3+) compare favorably with measurements made by inelastic neutron scattering. In addition, we calculate the absorption spectra for Tb(3+), Dy(3+), Ho(3+), TM(3+), and Yb(3+) in their respective arsenide compounds at 4.2, 77, and 300 K. From these calculations, we show the transitions between the levels of the lowest two J multiplets for each of the ions ... Rare-earth arsenides, Rare- earth spectra.

Book Synopsis Optical Spectra of Ce and Pr by : Karl Gürs
Download or read book Optical Spectra of Ce and Pr written by Karl Gürs and published by Springer. This book was released on 1993 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume opens a series dealing with the optical spectra of rare earth ions in inorganic solid rare earth compounds, host crystals, and glasses. Ions of the elements Ce to Lu in host materials serve as optically active centers in commercially used phosphors and in solid state lasers. Thus, much experimental and theoretical work on their spectra has been performed and is still in progress. Both a phenomenological description of the experimental spectra as well as the appropriate energy level diagrams are given. The topics of the present volume are the optical spectra of cerium and praseodymium ions in solid host materials. Especially the spectra of Pr3+ ions continue to be studied intensively because of laser activity in the visible region and the experimentally observed upconversion phenomena. The great variety of host materials includes praseodymium halids, PR3+-doped rare earth halides like LaF3 or LaCL3, fluorite, garnets, borates, phosphates, double nitrates or glasses.
