Description

Green-Emitting Luminescent Materials: Phosphor Materials, Properties, Synthesis, and Characterization summarizes the present knowledge on the use, advances, advantages and weaknesses of a large number of experimental techniques that are available for the characterization of inorganic green emitting phosphors. Different characterization techniques with spectroscopy are classified according to the group of the technique used, the information they can provide, or the materials that they are used to observe. The authors describe the main characteristics of the techniques and their operation principles and give various examples of their use, presenting them in comparison with one another. This book is suitable for researchers and practitioners in academia, research and development in the disciplines of materials science and engineering, chemistry and physics.

Key Features

  • Presents a concise overview of different types of green emitting phosphor materials for solid state lighting and other relevant application
  • Reviews and compares the most relevant characterization methods of inorganic green-emitting phosphors
  • Addresses fundamentals, luminescence mechanisms and key optical materials, including synthesis methods
