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 ‘Experimental Methods for Phosphor Evaluation and Characterization’ addresses the theoretical and experimental methods for phosphor evaluation and characterization. The chapters in the book cover: First principle and DFT analysis of optical, structural, and chemical properties of phosphors Phosphor design and tuning through structure and solid solution Design for IR, NIR, and narrowband emission and thermally stable phosphors and nanophosphors Detailed illustration for measurement of the absolute photoluminescence quantum yield of phosphors Phosphor analysis through photoionization, high pressure, and synchrotron radiation studies

This book presents the fundamental scientific principles of long afterglow phosphorescent materials and a comprehensive review of both commercialized afterglow materials and the latest advances in the development of novel long afterglow materials. It is designed to supply much needed information about inorganic and organic afterglow materials, including detailed treatment of structure, classification, preparation techniques, characterization, surface modification chemistry, and optical measurements. Special attention is given to technological applications such as photovoltaics, photocatalytic reactions, and lighting and molecular sensing. Although traditional long afterglow phosphors have been widely investigated and used in industry, and significant efforts have recently been made toward the use of these materials for bioimaging, there is to date no scientific monograph dedicated to afterglow materials. This book not only provides a beginners’ guide to the fundamentals of afterglow luminescence and materials, but also gives skilled researchers essential updates on emerging trends and efforts. The work provides a special focus on organic afterglow materials, which offer several advantages such as light-weight, flexible, and wide varieties; mild preparation conditions; and good processability. This book is aimed at postgraduate students, researchers, and technologists who are engaged in the synthesis, development, and commercialization of afterglow materials. It represents essential reading on interdisciplinary frontiers in the materials science, chemistry, photophysics, and biological aspects of afterglow materials.

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.

Chromic or colour related phenomena are produced in response to a chemical or physical stimulus. This new edition will update the information on all those areas where chemicals or materials interact with light to produce colour, a colour change, or luminescence especially in the imaging, analysis, lighting and display areas. The book has been restructured to show greater emphasis on applications where 'coloured' compounds are used to transfer energy or manipulate light in some way therefore reducing the details on classical dyes and pigments. In the past eight years, since the previous edition, there has been a remarkable increase in the number of papers and reviews being produced reflecting the growth of interest in this area. This ongoing research interest is matched by a large number of new technological applications gaining commercial value covering e.g. biomedical areas, energy, data storage, physical colour, bio-inspired materials and photonics. This book appeals to industrial chemists, professionals, postgraduates and as high level recommended reading for colour technology courses.

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.

This book provides fundamental knowledge of ceramics science and technology in a compact volume. Based on inorganic chemistry, it is intended as a reader for graduate students and young researchers beginning work in ceramics. The importance of the book is that it provides a scientific understanding of structure, properties, and processing from the chemical aspect, leading to creation of future ceramics. Ceramics have high hardness, strength, thermal and chemical stability, as well as various electromagnetic functions. To take full advantage of ceramics, their use has been advanced to engineering and electronic ceramics. Most ceramics have been fabricated by powder processing, and new technologies have also evolved such as CVD and sol-gel methods: new ceramics aimed at new functions of highly pure oxides and artificial nitrides, carbides, and borides; fine ceramics focused on precise control of composition and microstructure; and design of unique morphology, such as nanoparticles, nanofibers, nanosheets, mesoporous materials, and hybrids. Materials are composed of atoms and molecules. They are assembled into crystals and are amorphous, leading to 3-D micro/nano structures. In addition to the topics described above, this book shows the importance of chemistry for materials design at the nanometer scale, and that chemistry develops new fields of environment, energy, informatics, biomaterials, and other areas.
