The phenomenon of luminescence, its different forms with distinct mechanisms, and their applications in diverse fields have equally fascinated and engrossed technologists, engineers, and scientists from different disciplines. Luminescence is emission of light by a substance not resulting from heat, it is thus a form of cold body radiation.Luminescent materials are called phosphors. Review of the challenging work in the pursuit of finding better phosphor materials, and innovative applications; carried out by scientists world-wide, and a little contribution in form of the results of research on Silicate and Vanadate based materials, will of interest to many students, teachers and researcher of this field.

Since the discovery of the transistor in 1948, the study of the solid state has been burgeoning. Recently, cold fusion and the ceramic superconductor have given cause for excitement. There are two approaches possible to this area of science, namely, that of solid state physics and solid state chemistry, although both overlap extensively. The former is more concerned with electronic states in solids (including electromagnetics) whereas the latter is more concerned with interactions of atoms in solids. The area of solid state physics is well documented, however, there are very few texts which deal with solid state chemistry. Luminescence and the Solid State has been written to fulfil this need. The concepts regarding luminescence and phosphors are unique and have been covered extensively providing a useful reference source for anyone requiring such knowledge as a basis for further study. The discussion on the defect state, which is handled in chapter two, can be applied to many other systems, e.g. ceramic superconductors. The book has extensive, useful equations and figures, the derivations of which are simple and easy to follow. This useful, comprehensive text can be used for self-study and should also prove invaluable in a graduate study as an introduction to the solid state and luminescence.

The idea for this book arose out of the realization that, although excellent surveys and a phosphor handbook are available, there is no single source covering the area of phosphate based phosphors especially for lamp industry. Moreover, as this field gets only limited attention in most general books on luminescence, there is a clear need for a book in which attention is specifically directed toward this rapidly growing field of solid state lighting and its many applications. This book is aimed at providing a sound introduction to the synthesis and optical characterization of phosphate phosphor for undergraduate and graduate students as well as teachers and researchers. The book provides guidance through the multidisciplinary field of solid state lighting specially phosphate phosphors for beginners, scientists and engineers from universities, research organizations, and especially industry. In order to make it useful for a wide audience, both fundamentals and applications are discussed, together.

Rare-Earth-Activated Phosphors: Chemistry and Applications outlines important fundamentals and properties and explores successful application that address key problems across the sciences. Sections introduce phosphors and luminescence, explore their properties, characteristics, synthesis and degradation and highlight key applications across telecommunications, lighting, electroluminescent devices, (bio-)analytical sensors, bio-imaging set-ups, drug delivery and sustainable energy devices. Drawing on the knowledge of an expert team of contributors, the book provides useful insight into successfully harnessing the properties of rare earth activated phosphors for a range of important applications. Rare-earth nano-phosphors offer an interesting array of characteristics, including sharp emission bands, exceptional optical damage thresholds, low toxicity, high selectivity and stability, and long luminescence lifetimes. Understanding these properties can help researchers effectively manipulate them for a range of important applications. Provides a good introduction to the useful properties and characteristics of rare earth activated phosphors Analyzes the use of rare earth activated phosphors for a broad variety of important applications, bridging the gap between theory and application Encourages further discourse and development for improving the energy-efficiency of devices based on rare earth activated phosphors

A benchmark publication, the first edition of the Phosphor Handbook, published in 1998, set the standard for references in the field. The second edition, updated and published in 2007, began exploring new and emerging fields. However, in the last 14 years, since the second edition was published, many notable advances and broader phosphor applications have occurred. Completely revised, updated, and expanded into three separate volumes, this third edition of the Handbook covers the most recent developments in phosphor research, characterization, and applications. This volume on ‘Fundamentals of Luminescence’ elucidates the theoretical background and fundamental properties of luminescence as applied to solid-state phosphor materials. The book includes the chapters that cover: Basic principles of luminescence, the principal phosphor materials, and their optical properties New developments in principal phosphors in nitrides, perovskite, and silicon carbide Revised lanthanide level locations and its impact on phosphor performance Detailed descriptions of energy transfer and upconversion processes in bulk and nanoscaled particles and core-shell structures Rapid developing organic and polymer luminescent materials and devices
