This volume addresses the area of practical phosphors-materials that emit light, generally in the visible region of the spectrum, and find application in many technologies ranging from signing and display to sensing and lighting. This unique book provides a compendium of materials and luminescent properties of phosphors written in a "cookbook" style that describes the preparation conditions as well as the main optical properties of some 200 inorganic phosphors. All entries are categorized in terms of the chemical composition of the phosphors and luminescence output wavelengths. The book serves as a guide to anyone interested in preparing phosphors, whether experienced in the field or not.
