"The focus of the book is to explore metal oxides exhibiting a high optical transmittance as applicable in the field of light-emitting diodes (LED), photo-catalysts, and so forth. It provides exposure to structural and chemical parameters of optically active metal oxides as a phosphor, and innovative/currently demanded synthesis methods and their proper characterization. it further covers applications such as optical thermometry, scintillation, anti-counterfeit, solid state lighting and spectral modifier for solar cell, VUV application, and long persistent light emission phenomenon. Reviews selection of structurally and functionally active materials for effective synthesis of metal oxides. Exclusively covers large number of areas of applications of the luminescent metal oxides. Cover various aspects of metal oxide research including synthesis and applications. Includes chapters on synthesis related predictions using machine learning. Discusses radiation dosimetry and bio-imaging aspects. This book is aimed at researchers and graduate students in materials science and phosphor technology"--
