Book excerpt: Phosphor materials find wide applications ranging from fluorescent display to luminescence immunoassay. These materials essentially convert one type of energy in to visible radiation and hence, phosphor materials are called optical transducer. They are generally crystalline in nature. Phosphors with high quantum efficiency, effective excitation and absorption, colour parity, longer ifetime and lower cost, as well as better morphology are required. Surface properties have important function for hosphors.Spherical phosphors are optimum morphology in application. The spherical particles are easy to be packed density so that the screen and display can obtain high definition. In addition the dense packed small particles can prevent phosphors from aging.

This book was released on 2020-01-01 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrothermally synthesized rare-earth oxide compounds such as Nd2O3, Dy2O3, Gd2O3, Eu2O3, Y2O3, etc. and hydroxide ompounds such as Y(OH)3, Dy(OH)3, Gd(OH)3, Eu(OH)3, Tb(OH)3, etc. have been widely used as high-performance luminescent devices, atalysts and other functional materials based on the electronic, optical and chemical characteristics arising from their 4f electrons. In the rystallization process, surfactant molecules adsorbed on the crystal nuclei serve not only as a growth director but also as a protector to prevent from aggregation of the product. As a result, nanorods were produced. Cetyl trimethyl ammonium bromide (CTAB) and exadecylamine (HDA) surfactant are plays a key role in controlling the growth and production of oxide phosphors in the hydrothermal method.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: METAL OXIDE NANOCOMPOSITE THIN FILMS FOR OPTOELECTRONIC DEVICE APPLICATIONS The book provides insight into the fundamental aspects, latest research, synthesis route development, preparation, and future applications of metal oxide nanocomposite thin films. The fabrication of thin film-based materials is important to the future production of safe, efficient, and affordable energy as the devices convert sunlight into electricity. Thin film devices allow excellent interface engineering for high-performance printable solar cells as their structures are highly reliable and stand-alone systems can provide the required megawatts. They have been used as power sources in solar home systems, remote buildings, water pumping, megawatt-scale power plants, satellites, communications, and space vehicles. Metal Oxide Nanocomposite Thin Films for Optoelectronic Device Applications covers the basics of advanced nanometal oxide-based materials, their synthesis, characterization, and applications, and all the updated information on optoelectronics. Topics discussed include the implications of metal oxide thin films, which are critical for device fabrications. It provides updated information on the economic aspect and toxicity, with great focus paid to display applications, and covers some core areas of nanotechnology, which are particularly concerned with optoelectronics and the available technologies. The book concludes with insights into the role of nanotechnology and the physics behind photovoltaics. Audience The book will be an important volume for electronics and electrical engineers, nanotechnologists, materials scientists, inorganic chemists in academic research, and those in industries, exploring the applications of nanoparticles in semiconductors, power electronics, and more.

Book excerpt: Developments in Geochemistry, Volume 2: Rare Earth Element Geochemistry presents the remarkable developments in the chemistry and geochemistry of the rare earth elements. This book discusses the analytical techniques and the recognition that rare earth fractionation occurs naturally in different ways. Organized into 13 chapters, this volume begins with an overview of the wide array of types and sizes of the cation coordination polyhedral in rock-forming minerals. This text then examines the application of rare earth element abundances to petrogenetic problems that has centered on the evolution of igneous rocks. Other chapters consider the matching of observed rare earth element abundances with those provided by the theoretical modeling of petrogenetic processes. This book discusses as well the hypotheses on the genesis of a rock or mineral suite. The final chapter deals with the principal analytical methods. This book is a valuable resource for undergraduates, lecturers, and researchers who study petrology and geochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The Springer Handbook of Nanomaterials covers the description of materials which have dimension on the "nanoscale". The description of the nanomaterials in this Handbook follows the thorough but concise explanation of the synergy of structure, properties, processing and applications of the given material. The Handbook mainly describes materials in their solid phase; exceptions might be e.g. small sized liquid aerosols or gas bubbles in liquids. The materials are organized by their dimensionality. Zero dimensional structures collect clusters, nanoparticles and quantum dots, one dimensional are nanowires and nanotubes, while two dimensional are represented by thin films and surfaces. The chapters in these larger topics are written on a specific materials and dimensionality combination, e.g. ceramic nanowires. Chapters are authored by well-established and well-known scientists of the particular field. They have measurable part of publications and an important role in establishing new knowledge of the particular field.
