Hardcover. Etat : Good. Hardcover, xii + 196 pages, index. Printed in Germany. Ex-university library, marked "withdrawn": stamped all outer page edges (4 external stamps in total), internal library markings limited to rear pastedown (a barcode label and two stamps). Interior remains in very good condition throughout: clean, untanned, with unmarked text and firm binding. Negligible, very minor wear to very tips of some page corners; no other internal creasing. Boards show a hint of sunning, two slightly darker areas indicative of removed labels (lower spine and lower front at spine), gently bent corners with short creases; tips of corners with short, superficial, closed edge-nicks and a bit of scuffing; tiny creases to spine ends. Published without a dust jacket. --- This book deals with the mutual interaction and energy transfer between electronic defect states of F centers and defect ions (e.g. rare earth elements) and neighbouring molecular defects (OH-, CN-) in alkali halides. These model defect systems exhibit a very intriguing and ambiguous character because they behave like isolated defects in one instance but like supermolecules in others. The text gives an overview of the topic and discusses possible applications. It covers a wide range of spectroscopic methods applied to the systems and reviews several approaches for their theoretical interpretation. It includes more than 100 illustrations, figures and tables as well as many previously unpublished results. This book provides a valuable resource for further studies into this and related fields.…

Etat : Sehr gut. Zustand: Sehr gut | Seiten: 372 | Sprache: Englisch | Produktart: Bücher | It has been noted several times previously that the Rare Earths (RE), a sequence of elements with atomic numbers in the range from 58 (Ce) to 71 (Lu), are neither earths nor particularly rare. They are metals, whose ores are often found together with oxides of the ¿alkaline earths¿ (Ca, Mg), staples of the building industry, th while Cerium, for example, is the 25 most abundant element in the Earth¿s crust. However, the chemical similarity of all REs to each other and to Lanthanum, reflected in their alternative descriptor, Lanthanoids, made extraction of the separate elements difficult until technical advances in the 1960s kick-started the modern era of RE science. The most widespread commercial use of RE metals at present is in the prod- tion of super-strong permanent magnets, containing Neodymium: check your refrigerator door for an example. RE ferromagnetism arises from the angular momentum of electrons in partially filled 4f atomic shells. In chemical compounds of RE with non-metals, the 4f shell is surrounded by filled 5s and 5p orbitals, 1 2 while bonding involves the outerlying 5d and 6s electrons, resulting (usually) in 3+ 3+ a RE ion that is chemically similar to La . (RE may also be found in a divalent charge state, with an ¿exträ electron in the 5d shell. ) Hence the sequence of 3+ 3+ trivalent ions from Ce to Yb is characterised by a 4f shell occupation that rises from 1 to 13 electrons.…

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - This book provides a snapshot of recent progress in the field of rare-earth-doped group III-nitride semiconductors, especially GaN, but extending to AlN and the alloys AlGaN, AlInN and InGaN. This material class is currently enjoying an upsurge in interest due to its ideal suitability for both optoelectronic and spintronic applications. The text first introduces the reader to the historical background and the major theoretical challenges presented when 4f electron systems are embedded in a semiconductor matrix. It details the preparation of samples for experimental study, either by in-situ growth or ion implantation/annealing, and describes their microscopic structural characterisation. Optical spectroscopy is a dominant theme, complicated by site multiplicity, whether in homogeneous hosts or in heterostructures such as quantum dots, and enlivened by the abiding fascination of the energy transfer mechanism between the host material and the lumophore. Finally, the rapid progress towards prospective optoelectronic and spintronic devices is presented along with several examples.…
