Persistent Phosphors (eBook)

Persistent Phosphors: From Fundamentals to Applications provides an introduction to the key synthesis methods, characterization methods, physical mechanisms, and applications of this important luminescent materials system. The book covers basic persistent phosphorescence, introducing concepts such as emission, luminescence, phosphorescence, persistent phosphorescence and the development of persistent phosphors. Then, synthesis methods are reviewed and the connections between synthesis methods and improved materials properties are discussed. Characterization methods to investigate the trapping and de-trapping mechanism are also presented. Other sections cover the theoretical framework and energy band engineering models and materials with a focus on activators, hosts, emission bands and excitation bands. Finally, the most relevant applications of persistent phosphors are included for use in displays, safety signs, bio-labels and energy.

Persistent Phosphors is an invaluable reference for materials scientists and engineers in academia and R&D. It is a key resource for chemists and physicists.

• Presents characterization techniques to reveal the photophysical and photochemical properties of defects for this important category of luminescent materials
• Discusses the structural role of defects in polycrystals and the capture-storing-migration-release progress of excited carriers
• Demonstrates the synthesis routes and potential applications for persistent phosphor materials

Jianrong Qiu received his PhD from Okayama University, Japan in 1992. He worked at the Japan Science and Technology Agency as a chief researcher, Cornell University as a research associate fellow and Zhejiang University as a professor from 1995 to 2008. He was Cheung Kong chair professor of South China University of Technology from 2009 to 2014, and is now chair professor of Zhejiang University, China.
He has authored more than 500 articles and has around 16 000 SCI citations to his papers. He has co-authored one book in English (Springer-Verlag) and one book in Japanese (Kagaku Dojin, Japan). He was the author of many chapters (more than 20) to various books. He has given more than 120 plenary or invited lectures in international conferences. He received the Young Scientist Award from the Rare-earth Society of Japan in 1999, Otto-Schott Research Award from the Ernst Abbe Fund, Germany in 2005, Academic Award from the Ceramics Society of Japan in 2007, and G. W. Morey Award from the American Ceramic Society in 2015. He serves as associate editor or editor of the Int. J. Appl. Glass Sci., J. Non-Cryst. Solids, J. Asian Ceram. Soc., J. Ceram. Soc. Jpn, J. Chinese Ceram. Soc., and Front. Mater.-Glass. Sci. His current research interests are photonic materials (luminescent materials and nonlinear optical materials) and femtosecond laser interaction with materials.
