Measuring the properties of phosphors is an essential step in developing and selecting phosphors for specific applications. Consisting of chapters drawn from the second edition of the best-selling Handbook of Phosphors, Measurements of Phosphor Properties outlines various methods for characterizing and measuring the optical and luminescence properties of phosphors. The book covers measurement in the vacuum-ultraviolet region, measurement of particle size and optical properties of phosphor powders, and relevant aspects of color vision in the human eye. It details the optical properties of powder layers, color vision, and other miscellanies. It concludes with a detailed history of phosphor technology and industry.
