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.

This book was released on 1970 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents the results of a study of the luminescence of rare earth doped ionic materials. The first part discusses the application of X-ray-stimulated luminescence to the detection of trivalent rare earth impurities. Characteristic luminescent wavelengths allow the identification of individual rare earths. The application of the technique to the assessment of single crystals and the appropriate starting material is discussed. The second part considers the advantages offered by the use of an X-ray source as a pumping source in optical spectroscopy. The examples given to illustrate these advantages cover the appraisal of poor quality material, and the enhancement of one emission with respect to another. (Author).

This book was released on 2013 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rare-earth-doped solids are promising materials as light-matter interfaces for quantum applications. In particular, europium-doped yttrium orthosilicate crystal (Eu3+:Y2SiO5) shows coherence properties and a ground-state energy-level structure suitable for quantum memory applications. Within the european project QuRep, spectroscopic investigations of this material are reported in order to determine the optimal conditions (in terms of material's purity or ions concentration) for obtaining high performance quantum memories. Two crystal growth techniques (Czochralski and melting zone) are also used in order to refine the growth conditions for this material. The europium optical transition 7F0 - 5D0 is investigated by high resolution-absorption and photon echo techniques in order to study the absorption coefficient peak, the inhomogeneous linewidth and the optical coherence lifetime as function of different conditions. The hyperfine structure of the two europium isotopes (151Eu and 153Eu) is also analyzed by applying an external static magnetic field. Coherent Raman Scattering measurements are performed in order to measure the hyperfine coherence lifetime in 151/153Eu3+:Y2SiO5 found to be in the range of 10-20 ms at zero magnetic field.

Download or read book Semimetals written by N.B. Brandt and published by Elsevier. This book was released on 2012-12-02 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: ``Semimetals'' presents, for the first time in the literature, a consistent and unifying treatment of semimetals (As, Bi, Sb, Bi-Sb alloys, graphite and its compounds). It describes their structural features and their electric, magnetic, galvanomagnetic, thermoelectric, optical, magneto-optical, acoustic, thermal, and mechanical properties on the basis of modern concepts of the electron and phonon energy spectra. The book discusses in detail the character of the changes in the energy spectrum and properties of semimetals due to temperature variations, application of a magnetic field, pressure, anisotropic strain, doping by donor, acceptor and neutral impurities, which indicate how the above properties may be altered and how materials with preassigned parameters can be produced. Furthermore, it discusses specific phenomena associated with low dimensionality and the very low carrier density, such as quantum oscillations and magnetoplasma behaviour.

Download or read book Evaluation of a Stoichiometric Rare Earth Crystal for Quantum Computing written by Rose Ahlefeldt and published by . This book was released on 2013 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a spectroscopic study of the 7F0-5D0 transition of Eu3+ in EuCl3.6H2O, which is used to evaluate the potential performance of a quantum computing system implemented in EuCl3.6H2O and, more generally, in stoichiometric rare earth crystals. EuCl3.6H2O has one of the narrowest optical inhomogeneous linewidths of any solid but this linewidth is shown to be still much larger than that required for practical quantum computing in a rare earth crystal. To assess the possibility of reducing the linwidth, the contributions of isotopic impurities to both the optical linewidth and line structure were investigated, and ligand isotopes were identified as a major source of both inhomogeneous broadening and structure on the optical transition, suggesting that the linewidth could be substantially reduced by isotopically purifying EuCl3.6H2O. The effect of ligand isotopes on the optical lifetime and coherence time was also investigated. It was found that fully deuterating the crystal to EuCl3.6D2O substantially improves both the lifetime and coherence time. The satellite lines formed in the optical spectrum of a rare earth crystal when it is doped with another rare earth are proposed as qubits. A crucial step in characterising EuCl3.6H2O for quantum computing is associating these satellite lines in EuCl3.6H2O with crystallographic sites. A new method for associating sites with lines, which works for low symmetry crystals such as EuCl3.6H2O, is presented. This method involves modelling the splitting of the ground state hyperfine levels caused by the magnetic dipole-dipole interaction between a Kramers dopant and the Eu3+ ion. Using this method, most of the outer satellite lines in rare earth doped EuCl3.6H2O were assigned to crystallographic sites. It has been proposed that the electronic interactions between these satellite lines be used to enact two-qubit gates in a rare earth quantum computer. These interactions were measured between a number of different satellite lines using a new two-laser spectral holeburning technique. Interactions of up to 46.081 +- 0.005 MHz were observed, and this was the first time that electronic interactions between weakly coupled rare earth ions had been measured. The two most common interactions identified between rare earth ions in solids are electric dipole-dipole and exchange, but the observed interactions are stronger than expected from a electric dipole-dipole model and occur at too large a distance to be superexchange. It is shown that the development of a moderate-sized quantum processor, one with more than 10 qubits, in a stoichiometric rare earth crystal is feasible provided that the optical inhomogeneous linewidth is reduced below 1 MHz. Demonstrations of three or four qubit devices should be possible using existing materials.
