Fluorescent Lamp Phosphors


Book Description

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.

Practical Applications of Phosphors


Book Description

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.
