Dr. K.N. Shinde is Director of R & D Cell at N.S. Science and Arts College, Bhadrawati, Dist. Chandrapur, India. He has published many research papers in various journals on phosphor materials for lamp industry. He obtained his doctoral degree in Physics-Materials science (interdisciplinary) from R.T.M. Nagpur University, India. His research interests are synthesis of nanocrystalline luminescent materials and exploring novel materials and study their PL and TL properties.

Dr. S.J. Dhoble obtained his Ph.D. degree in 1992 on Solid State Physics from Nagpur University, Nagpur. He is presently working as an Associate Professor in Department of Physics, R.T.M. Nagpur University, Nagpur, India. During his research carrier, he has been involved in the synthesis and characterization of solid state lighting nanomaterials as well as development of radiation dosimetry phosphors using thermoluminescence, mechanoluminescence and lyoluminescence techniques. Dr. Dhoble published several research papers in International reviewed journals on solid-state lighting, LEDs, radiation dosimetry and laser materials. He is an executive member of Luminescence Society of India.

Introduction.- Basic Mechanisms of Photoluminescence.- Synthesis of Phosphate Phosphors.- Methods of Measurements (Instrumentation).- Some Orthophosphate Phosphors.- Some Halophosphate Phosphors.- Some Novel Phosphate Phosphors.- Current Progress in Solid State Lighting.

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.
