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.

A benchmark publication, the first edition of the Phosphor Handbook set the standard for references in this field.

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.

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

Research on fertilizers and munitions is an important part of the activities of the Tennessee Valley Authority in promoting sound utilization of the Nation's soil resources and contributing to the national defense. In the course of this research, the staff of the Division of Chemical Engineering has obtained from the technical literature and from experimental investigations a great deal of basic information on phosphorus and on many compounds of phosphorus that are of current or potential significance in the production of fertilizers and munitions.

The photo-excitation spectral emission properties of 10 of the 14 NBS standard phosphor samples have been determined.Pressed tablets of the phosphors were excited by radiation from a mercury arc lamp, passing through a narrow band-pass filter to obtain either 2537A or 3650A excitation.The measurement system is described,correction of the data is discussed, and the spectral emission data are presented.Relative quantum efficiencies were calculated.The results are compared with measurements reported by two other laboratories.(Author).

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.
