It is a matter of pleasure to present the Luminescence studies on Sm3+, Eu3+, Dy3+, Er3+ and Er3+/Yb3+ ions in potassium niobate silicate glasses. The prime objectives of this book are: To prepare Potassium Niobate Silicate (K- Nb- Si) glasses doped Sm3+, Eu3+, Dy3+, Er3+ and Er3+/Yb3+ ions To characterize and optimize the prepared glasses by the conventional spectroscopic techniques like absorption, emission, decay, etc. measurements. To identify the optimum concentrations of dopant ions for efficient luminescence. To find lifetime of the emission level of rare earth ion by increasing active...

It is a pleasure to present the book provides a comprehensive and up to date account of the EPR and Luminescence Studies on metal ions and rare earth doped glasses. This book has been written in a simple and lucid manner. The book only all inclusive dealing with EPR and optical studies. This book continues to be a resource for Optical Engineers, Researchers and Graduate Students. Every effort has been made to make the treatment simple and comprehensive. The topics are explained with the help of clear diagrams, S.I. units are used throughout the book. In spite of our best efforts, some errors...
