Metal Oxide-Based Phosphors: Properties and Applications focuses on the basic principles, experimental techniques, and various applications of luminescent materials derived from metal oxides. The book is divided into three parts, with Part One presenting the fundamentals of luminescent materials and experimental methods, including different synthesis and characterization techniques. Part Two provides strategies to enhance luminescence through various host matrices, constructing hybrid phosphors with polymeric materials, and doping with non-rare earth elements. Finally, Part Three explores recent developments of metal oxide-based phosphors in various applications, including photovoltaics, solid-state lighting, anti-counterfeiting, radiation dosimeters, and chemical sensors. Luminescent materials show enormous potential in a wide range of applications, such as solid-state lighting, energy, display imaging, and optical thermometry. Developing novel metal oxide-based phosphors and exploring green technologies and methods for the preparation of high-performance phosphor materials is therefore vital for a number of industries.
