This new book highlights the link between the luminescence phenomena of phosphors used in different displays. Both fluorescence (used in display phosphors) and phosphorescence (used in after glow phosphors and storage phosphors) mechanisms and the efforts made in phosphor synthesis to reduce the interference of one on another are dealt with in detail.

Drawn from the second edition of the best-selling Phosphor Handbook, Practical Applications of Phosphors outlines methods for the production of various phosphors and discusses a broad spectrum of applications. Beginning with methods for synthesis and related technologies, the book sets the stage by classifying and then explaining practical phosphors according to usage. It describes the operating principle and structure of phosphor devices and the phosphor characteristics required for a given device, then covers the manufacturing processes and characteristics of phosphors. The book discusses research and development currently under way on phosphors with potential for practical usage and touches briefly on phosphors that have played a historical role, but are no longer of practical use. It provides a comprehensive treatment of applications including lamps and cathode-ray tubes, x-ray and ionizing radiation, and for vacuum fluorescent and field emission displays and covers inorganic and organic electroluminescence materials. The book also covers phosphors for plasma displays, organic fluorescent pigments, and phosphors used in a variety of other practical applications. Emphasizing the practical and cutting-edge nature of the material included, the editors round out their coverage with a discussion of solid-state and organic laser materials.

This comprehensive treatment of fluorescent lamp phosphors is the first published description of methods for their manufacture. It discusses the various factors controlling the selection of specific phosphors for use in lamps, and is unique in its systematic application of group theory to the problem of explaining the excitation and emission spectra in terms of crystal structure of the host material and the energy levels of the added foreign ions which are the so-called activators responsible for fluorescence. Unusual topics from various specialized fields are included since phosphor science requires a knowledge of several branches of physics, chemistry, and crystallography as well as some aspects of ceramic technology. The basic principles of the theory of atomic spectra, group theory, and the use of character tables for the thirty-two crystallographic point groups are included for convenient reference. The appendix contains essential tables for dealing with the spectra of ions in crystals.

Persistent Phosphors: From Fundamentals to Applications provides an introduction to the key synthesis methods, characterization methods, physical mechanisms, and applications of this important luminescent materials system. The book covers basic persistent phosphorescence, introducing concepts such as emission, luminescence, phosphorescence, persistent phosphorescence and the development of persistent phosphors. Then, synthesis methods are reviewed and the connections between synthesis methods and improved materials properties are discussed. Characterization methods to investigate the trapping and de-trapping mechanism are also presented. Other sections cover the theoretical framework and energy band engineering models and materials with a focus on activators, hosts, emission bands and excitation bands. Finally, the most relevant applications of persistent phosphors are included for use in displays, safety signs, bio-labels and energy. Persistent Phosphors is an invaluable reference for materials scientists and engineers in academia and R&D. It is a key resource for chemists and physicists. Presents characterization techniques to reveal the photophysical and photochemical properties of defects for this important category of luminescent materials Discusses the structural role of defects in polycrystals and the capture-storing-migration-release progress of excited carriers Demonstrates the synthesis routes and potential applications for persistent phosphor materials

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.

A benchmark publication, the first edition of the Phosphor Handbook, published in 1998, set the standard for references in the field. The second edition, updated and published in 2007, began exploring new and emerging fields. However, in the last 14 years, since the second edition was published, many notable advances and broader phosphor applications have occurred. Completely revised, updated, and expanded into three separate volumes, this third edition of the Handbook covers the most recent developments in phosphor research, characterization, and applications. This volume on ‘Novel Phosphors, Synthesis, and Applications’ provides the descriptions of synthesis and optical properties of phosphors used in different applications, including the novel phosphors for some newly developed applications. The chapters in this book cover: Various LED-based phosphors and their synthesis and applications Ingenious integrated smart phosphors and their novel optoelectronic and photonic devices Quantum dot, single crystalline, and glass phosphors Upconversion nanoparticles for super-resolution imaging and photonic and biological applications Special phosphors for laser, OLED, energy storage, quantum cutting, thermometry, photosynthesis, AC-driven LED, and solar cells
