Infos

This book provides expert coverage of the physical properties of new non-crystalline solids-tellurite glass smart materials-and the latest applications of these materials, offering insights into innovative applications for radiation shielding, energy harvesting, laser devices, and temperature sensing, among others. In particular, there is a focus on optics, energy conversion technology and laser devices, structural and luminescence properties for laser applications, optothermal and optical properties in the presence of gold nanoparticles, and lanthanide doped zinc oxyfluoro-tellurite glass as a new smart material.

Additional chapters address the properties and uses of tellurite glasses in optical sensing, the significance of Near Infrared (NIR) emissions, solar cells, solar energy harvesting, luminescent displays, and the development of bioactive-based tellurite-lanthanide (Te-Ln) doped hydroxyapatite composites for biomedical applications.

As the world's reliance on glass increases, this book serves as a link between the latest findings on tellurite glasses and real-world technological advancement. Academic researchers and industry professionals alike will find this book a useful resource in keeping abreast of recent developments in the field.

Professor R. El-Mallawany is an Emeritus Professor of Solid State Physics at Menofia University, Egypt. He has taught physics for undergraduates & postgraduates for nearly four decades and has supervised and examined Ph.D. and M.Sc. theses at Egyptian and Arab Universities. He has also cooperated with American, European, and Asian universities concerning experimental & theoretical contributions in optical, electrical, thermal, elastic, and vibrational aspects of condensed matter physics Semiconducting Glasses. Prof. El-Mallawany both serves as a reviewer for international journals and has published numerous cited scientific articles, book chapters, and a handbook.

Furthermore, Prof. El-Mallawany has deepened his involvement in the international community through organizing and advising materials science and glass conferences. He has been invited by the European Office of Aerospace Research & Development (EOARD) to present several seminars in his area of expertise, and by the International Materials Institute (IMI), USA to present five video seminars to help researchers all over the world. Prof. El-Mallawany is a consultant for a number of universities regarding evaluation of scientific work leading to professorship in solid state physics. He has been the recipient of three Egyptian national awards.
