Spectroscopic Properties of Rare Earths in Optical Materials by Guokui Liu,Bernard Jacquier Pdf

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.

Tables for Emission Spectrographic Analysis of Rare Earth Elements by Ch. Kerekes Pdf

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.

Lasers and Excited States of Rare Earths by Renata Reisfeld,Christian K. Jorgensen Pdf

The possibility of stimulated light emission was discussed by Einstein in 1917, eight years before the quantum-mechanical description of energy levels of many-electron systems. Though it is imperative to use samples having optical properties greatly different from the stan dard continuous spectrum of opaque objects ("black body" radia tion) it is not always necessary to restrict the study to monatomic entities. Thus, spectral lines can be obtained (in absorption and in emission) from lanthanide compounds, containing from one to thir teen 4f electrons going from trivalent cerium to ytterbium, that are nearly as sharp as the ones from gaseous atoms. However, the presence of adjacent atoms modifies the simple picture of an isolated electron configuration, and in particular, it is possible to pump excited levels efficiently by energy transfer from species with intense absorption bands, such as the inter-shell transitions of other lanthanides and of thallium(I), lead(II) and bismuth(III) or the electron transfer bands of the uranyl ion or other complexes. On the other hand, it is possible to diminuish the mUlti-phonon relaxation (competing with sharp line luminescence) by selecting vitreous or crystalline materials with low phonon energies. Obviously, one cannot circumvent the conservation of energy by lasers, but they may have unprecedented consequences for the future by allowing nuclear fusion of light elements, effects of non-linear optics and time-resolved spectroscopy, besides the more conventional applications of coherent light beams with negligible angular extension.

An Atlas of High Resolution Spectra of Rare Earth Elements for Inductively Coupled Plasma Atomic Emission Spectroscopy by Benli Huang Pdf

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.

Nanostructured and Advanced Materials for Applications in Sensor, Optoelectronic and Photovoltaic Technology by Ashok K. Vaseashta,D. Dimova-Malinovska,J.M. Marshall Pdf

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.

An Atlas of High Resolution Spectra of Rare Earth Elements for ICP-AES by Benli Huang,Hai Ying,Pengyuan Yang,Xiaoru Wang,Sheng Gu,Zhigang Zhang,Zhixia Zhuang,Zhenhua Sun,Bing Li Pdf

Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) has been widely adopted as a routine analytical technique for elemental analysis in both industry and academia. However, spectral interference can be a major problem, particularly with such line-rich elements as the rare earth elements. An Atlas of High Resolution Spectra of Rare Earth Elements, which comes complete with a CD of spectra in full colour, is a reference source suitable for all analytical spectroscopists. Using some previously unpublished high resolution spectra, this atlas enables users of ICP-AES to select the best lines of any single rare earth element matrix. Clear instructions for the use of the accompanying CD are provided, which allows all adjacent interferent spectral profiles to be displayed and superimposed. Up-to-date and informative, this unique book will be welcomed as a practical and indispensable reference guide by all those who use ICP-AES for the analysis of rare earth elements.

Science and Technology of Rare Earth Materials by E C Subbarao Pdf

Science and Technology of Rare Earth Materials reviews the important aspects of the science and technology of rare earth materials, covering the entire spectrum from occurrence to extraction and purification, phase relationships, electronic structure, and applications. This book is organized into five sections encompassing 19 chapters. The occurrence, extraction, and production of rare earths are discussed in the first section, followed by purification methods employed for rare earths, together with the role of impurities on their behavior. The phase relations among the rare earth alloys, including a particular reference to the technologically important rare earth-cobalt alloys, and phase relations among the rare earth oxides are considered in the second section. The succeeding two sections focus on studies of the electronic structure of rare earth materials, with emphasis on the use of nuclear magnetic resonance and Mössbauer spectroscopy. Theoretical conceptions are set forth as well as the effect of crystal fields and valence fluctuations on the properties of rare earth systems. The final section describes some of the extensive current uses of rare earth materials such as in the steel industry and in permanent magnets, as well as emerging applications in catalysis, hydrogen storage, ferroelectrics, and fast ion conductors. This book is a valuable resource for researchers and students interested in rare earths.
