Rare-Earth-Activated Phosphors: Chemistry and Applications outlines important fundamentals and properties and explores successful application that address key problems across the sciences. Sections introduce phosphors and luminescence, explore their properties, characteristics, synthesis and degradation and highlight key applications across telecommunications, lighting, electroluminescent devices, (bio-)analytical sensors, bio-imaging set-ups, drug delivery and sustainable energy devices. Drawing on the knowledge of an expert team of contributors, the book provides useful insight into successfully harnessing the properties of rare earth activated phosphors for a range of important applications.

Rare-earth nano-phosphors offer an interesting array of characteristics, including sharp emission bands, exceptional optical damage thresholds, low toxicity, high selectivity and stability, and long luminescence lifetimes. Understanding these properties can help researchers effectively manipulate them for a range of important applications.
