The Magnesium Technology Symposium, the event on which this collection is based, is one of the largest yearly gatherings of magnesium specialists in the world. Papers represent all aspects of the field, ranging from primary production to applications to recycling. Moreover, papers explore everything from basic research findings to industrialization. Magnesium Technology 2017 covers a broad spectrum of current topics, including alloys and their properties; cast products and processing; wrought products and processing; forming, joining, and machining; corrosion and surface finishing; ecology; and structural applications. In addition, there is coverage of new and emerging applications.

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 ion concentration This book has been written in a simple and lucid manner. 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 might have crept. The authors do not take any legal responsibility for such errors and omissions.If they are brought to our notice, they will be corrected in next edition. Hope this book will be found useful be the research students"
