Book Description
From basic principles of luminescence to innovative technical applications, Phosphor Handbook will serve as the definitive resource on phosphors. Considering all the major changes in the field of phosphors, the editors have produced the most current and comprehensive reference available today. Contributed by noted worldwide scientists and engineers, the handbook serves a ready audience among researchers in the field of luminescence. This book completely describes: powder phosphors, including information on solid state laser materials and organic EL properties and technical applications of phosphors, including the principal classes of phosphors, procedures to synthesize and manufacture these phosphors, manner of deployment, and materials that emit light under various kinds of excitation current developments of phosphor materials required in advanced display technologies, such as UV Plasma Display and Field Emission Display (FED) experimental techniques characterizing materials in their initial and final forms Other provisos include: tutorials of fundamental physical and chemical properties of phosphor materials descriptions of optical properties of phosphor materials profiles on methods of synthesis and manufacture of all practical phosphors analysis of experimental procedures for the optical characterization of raw phosphors and the creation of display devices or lamps specification of physical and optical requirements for all applications of phosphors in lighting and display technologies Japanese industry has and will continue to play a key role in developing these applications, and many contributors to this volume acted as principals in the progress discussed. Display technologies will increase in importance, and no cohesive or comprehensive treatise exists - from basic to applied - on the nature, properties, synthesis, characterization, manufacture, and handling of phosphor materials in lighting and display technologies and applications. This exceptional handbook rectifies this deficiency, serving as the defining resource for all those engaged in research or in the application of phosphor materials - regardless of whether they are newcomers or veterans in this endeavor.

Book Description
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.

Book Description
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).
