Download or read book Fundamentals of Phosphors written by William M. Yen and published by CRC Press. This book was released on 2018-10-03 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing from the second edition of the best-selling Handbook of Phosphors, Fundamentals of Phosphors covers the principles and mechanisms of luminescence in detail and surveys the primary phosphor materials as well as their optical properties. The book addresses cutting-edge developments in phosphor science and technology including oxynitride phosphors and the impact of lanthanide level location on phosphor performance. Beginning with an explanation of the physics underlying luminescence mechanisms in solids, the book goes on to interpret various luminescence phenomena in inorganic and organic materials. This includes the interpretation of the luminescence of recently developed low-dimensional systems, such as quantum wells and dots. The book also discusses the excitation mechanisms by cathode-ray and ionizing radiation and by electric fields to produce electroluminescence. The book classifies phosphor materials according to the type of luminescence centers employed or the class of host materials used and interprets the optical properties of these materials, including their luminescence characteristics and mechanisms. Placing a strong emphasis on those materials that are important from a practical point of view, the coverage also includes those possessing no possibility for practical use but are important from a theoretical standpoint.
Download or read book Phosphate Phosphors for Solid State Lighting written by Kartik N. Shinde and published by Springer Science & Business Media. This book was released on 2012-12-15 with total page 275 pages. Available in PDF, EPUB and Kindle.
