Aimed at researchers and graduate students, this book provides up-to-date information about the electronic interactions that impact the optical properties of rare earth ions in solids. Its goal is to establish a connection between fundamental principles and the materials properties of rare-earth activated luminescent and laser optical materials. The theoretical survey and introduction to spectroscopic properties covers electronic energy level structure, intensities of optical transitions, ion-phonon interactions, line broadening, and energy transfer and up-conversion. An important aspect of the book lies in its deep and detailed discussions of materials properties and the potential of new applications such as optical storage, information processing, nanophotonics, and molecular probes that have been identified in recent experimental studies. This volume will be a valuable reference book on advanced topics of rare earth spectroscopy and materials science.

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.

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.

Produced by a group of scientists from the chemistry department of Xiamen U., China (as well as one author from the Chinese Ministry of Geology and Mineral Resources), this work contains data and profiles of high-resolution interferant spectra among rare earth elements (REEs). The aim of the book is to allow scientists to choose appropriate analytical spectral lines for the determination of REEs. Coincidence evaluation parameters for various elements are presented along with spectral coincidence profiles. The CD-ROM contains a program used to load the interferant spectra of arbitrarily selected REEs matrices around a selected prominent line.

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.
