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 the chemistry guiding these properties can help researchers effectively manipulate and harness them effectively for a whole range of important applications. Rare Earth Activated Phosphors outlines these fundamentals and properties, and explores their successful application to address key problems across the sciences. Beginning with an introduction to phosphors and luminescence, the book goes on to explore the properties, characteristics, synthesis and degradation of rare earth activated phosphors in Part 1. Part 2 then highlights 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, Rare Earth Activated Phosphors provides useful insight into successfully harnessing the properties of rare earth activated phosphors for a range of important applications. Provides a good introduction to the useful properties and characteristics of rare earth activated phosphors Analyses the use of rare earth activated phosphors for a broad variety of important applications, bridging the gap between theory and applicationEncourages further discourse and development for improving the energy-efficiency of devices based on rare earth activated phosphors
