Rare-Earth-Activated Phosphors: Chemistry and Applications outlines important fundamentals and properties and explores successful application that address key problems across the sciences. Sections introduce phosphors and luminescence, explore their properties, characteristics, synthesis and degradation and highlight key applications across telecommunications, lighting, electroluminescent devices, (bio-)analytical sensors, bio-imaging set-ups, drug delivery and sustainable energy devices. Drawing on the knowledge of an expert team of contributors, the book provides useful insight into successfully harnessing the properties of rare earth activated phosphors for a range of important applications. Rare-earth nano-phosphors offer an interesting array of characteristics, including sharp emission bands, exceptional optical damage thresholds, low toxicity, high selectivity and stability, and long luminescence lifetimes. Understanding these properties can help researchers effectively manipulate them for a range of important applications. Provides a good introduction to the useful properties and characteristics of rare earth activated phosphors Analyzes the use of rare earth activated phosphors for a broad variety of important applications, bridging the gap between theory and application Encourages further discourse and development for improving the energy-efficiency of devices based on rare earth activated phosphors

Drawing from the second edition of the best-selling Handbook of Phosphors, Fundamentals of Phosphors covers the principles and mechanisms of luminescence in detail and surveys the primary phosphor materials as well as their optical properties. The book addresses cutting-edge developments in phosphor science and technology including oxynitride phosphors and the impact of lanthanide level location on phosphor performance. Beginning with an explanation of the physics underlying luminescence mechanisms in solids, the book goes on to interpret various luminescence phenomena in inorganic and organic materials. This includes the interpretation of the luminescence of recently developed low-dimensional systems, such as quantum wells and dots. The book also discusses the excitation mechanisms by cathode-ray and ionizing radiation and by electric fields to produce electroluminescence. The book classifies phosphor materials according to the type of luminescence centers employed or the class of host materials used and interprets the optical properties of these materials, including their luminescence characteristics and mechanisms. Placing a strong emphasis on those materials that are important from a practical point of view, the coverage also includes those possessing no possibility for practical use but are important from a theoretical standpoint.

This collection of papers describes investigations of luminescence centers in II-VI crystal phosphors, ruby, and molecular crystals. These investigations were carried out using spectroscopy in a wide range of wavelengths, electron paramagnetic resonance, and polarization methods. The relationship between the thermal and optical depths of electron traps is considered specifically. The articles in this collection should be of interest to all scientists investigating the luminescence of solids.

A benchmark publication, the first edition of the Phosphor Handbook set the standard for references in this field. Completely revised and updated, this second edition explores new and emerging fields such as nanophosphors, nanomaterials, UV phosphors, quantum cutters, plasma display phosphors, sol-gel and other wet phosphor preparation techniques, preparation through combustion, bioluminescence phosphors and devices, and new laser materials such as OLED. It also contains new chapters on the applications of phosphors in solid state lighting, photoionization of luminescent centers in insulating phosphors, and recent developments in halide-based scintillators. The handbook provides a comprehensive description of phosphors with an emphasis on practical phosphors and their uses in various kinds of technological applications. It covers the fundamentals, namely the basic principles of luminescence, the principle phosphor materials, and their optical properties. The authors describe phosphors used in lamps, cathode-ray tubes, x-ray, and ionizing radiation detection. They cover common measurement methodology used to characterize phosphor properties, discuss a number of related items, and conclude with the history of phosphor technology and industry.

``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 presents an overview of up-converting phosphor (UCP), including UCP preparation, development of the rapid detection strips and UCP industrialization. It also discusses the wide clinical applications of this technology, such as in food poisoning, infectious diseases, drug-abuse and disaster rescue, where rapid point-of-care testing is often critical. Conventional testing methods are mainly based on gold immunochromatography, which relies heavily on results being read with the naked eye. However, up-converting phosphor technology (UPT) employs UCP particles as labels for rapid target detection. Unlike other conventional fluorescence techniques, UCP is excited by infrared light and emitted visible light. This anti-stokes phenomenon provides this special label with significant advantages, including zero background detection, high resistance to environmental influences (e.g. pH, salts, sample contamination), high sensitivity and quantitative detection. Systematically summarizing UCP technology and its wide applications, this book is a valuable resource for researchers and technicians in the field.
