Features

  • Highlights recent developments in traditional materials with improved properties
  • Discusses both the semiclassical and quantum mechanical approaches and deduces the key parameters of the bands, namely, Stokes shift, mirror low for absorption and emission, temperature dependence of the half-width, zero-phonon lines, and vibronic satellites, thereby keeping a good balance between theoretical and experimental chapters
  • Serves as a starting point for students and professionals to gain an understanding of various types and mechanisms of luminescence
  • Includes an extensive bibliography for further reading

Summary

This book concentrates on the luminescence and structural properties of the new generation of europium and terbium activated phosphors, associated phenomena, and related topics, from basic principles to the most recent discoveries. It summarizes the present state of the art in this rapidly growing field. The authors describe recent developments in the areas of rare earth doped phosphors and of some new materials or well-known materials with improved properties that open up new possibilities. The areas of focus include X-ray phosphors, phosphors for light-emitting devices, emissive displays, and ?uorescent lamps. The book comprises theoretical and experimental analysis of various properties of phosphors, research methods and preparation techniques, and some promising applications.
