Fluorescence and Phosphorescence

A brief survey of fluorescence and phosphorescence in inorganic luminophors (phosphors) is presented. This includes a short discussion on the preparation and composition of phosphors, the role of the matrix, and a discussion of activators, charge compensators, and flux. The nature and significance of absorption and emission spectra are discussed. A general model of the mechanism involved in excitation and luminescence (fluorescence and phosphorescence) is presented.
