Volume is indexed by Thomson Reuters BCI (WoS). This special volume consists of eight chapters consisting of seven Review papers and one Research paper. Luminescence Phenomena: An Introduction is the first Chapter contributed by KVR Murthy and HS Virk. It explains the basic phenomenon of Luminescence: Luminescence is "cold light", light from other sources of energy which can take place at normal and lower temperatures. The word luminescence was first used by a German physicist, Eilhardt Wiedemann, in 1888. In Latin Lumen means light. The materials exhibiting this phenomenon are known as Luminescent materials or Phosphors meaning light bearer in Greek. Luminescence is basically a phenomenon of emission of light from an insulator followed by prior absorption of energy from ionizing radiations like, X-rays, alpha, beta and gamma radiations. The energy lifts the atoms of the material into an excited state, and then, because excited states are unstable, the material undergoes another transition, back to its unexcited ground state, and the absorbed energy is liberated in the form of either light or heat or both. The excitation involves only the outermost electrons orbiting around the nuclei of the atoms. Luminescence efficiency depends on the degree of transformation of excitation energy into light, and there are relatively few materials that have sufficient luminescence efficiency to be of practical value.

The aim of this book is to give readers a broad review of topical worldwide advancements in theoretical and experimental facts, instrumentation and practical applications erudite by luminescent materials and their prospects in dealing with different types of luminescence like photoluminescence, electroluminescence, thermo-luminescence, triboluminescence, bioluminescence design and applications. The additional part of this book deals with the dynamics, rare-earth ions, photon down-/up-converting materials, luminescence dating, lifetime, bioluminescence microscopical perspectives and prospects towards the basic research or for more advanced applications. This book is divided into four main sections: luminescent materials and their associated phenomena; photo-physical properties and their emerging applications; thermoluminescence dating: from theory to applications, and bioluminescence perspectives and prospects. Individual chapters should serve the broad spectrum of common readers of diverse expertise, layman, students and researchers, who may in this book find easily elucidated fundamentals as well as progressive principles of specific subjects associated with these phenomena. This book was created by 14 contributions from experts in different fields of luminescence and technology from over 20 research institutes worldwide.

In this book, the authors give an up-to-date account of thermoluminescence (TL) and other thermally stimulated phenomena. Although most recent experimental results of TL in different materials are described in some detail, the main emphasis in the present book is on general processes, and the approach is more theoretical. Thus the details of the possible processes which can take place during the excitation of the sample, and during its heating, are carefully analysed. The methods for analysing TL glow curves are critically discussed, and recommendations as to their application are made. Also discussed is the expected behavior of these phenomena as functions of the experimental parameters, for example, dose of excitation. The consequences of the main applications of TL (for example, radiation dosimetry) are also discussed in detail as are the similarities and dissimilarities of other thermally stimulated phenomena, and the simultaneous measurements of the latter and TL.

This new book highlights the link between the luminescence phenomena of phosphors used in different displays. Both fluorescence (used in display phosphors) and phosphorescence (used in after glow phosphors and storage phosphors) mechanisms and the efforts made in phosphor synthesis to reduce the interference of one on another are dealt with in detail.

Written by a senior industry expert with nearly 40 years of hands-on experience, Cathodoluminescence and Photoluminescence: Theories and Practical Applications presents a thorough review of advances, challenges, and recommendations for improving photoluminescent (PL) and cathodoluminescent (CL) phosphor display devices in terms of energy efficiency, image quality, color fidelity, operational lifetime, and production cost. This book traces the development of cathode ray tubes (CRTs), PL and CL phosphor screens, and fluorescent lamps (FL) into modern phosphor display devices. The author relates luminescence phenomena and color to chemical composition, excitation mechanisms, energy conversion efficiencies, and bulk properties of phosphor particles. He also addresses image quality issues such as flickering, smearing, whitening, and contrast. Subsequent chapters focus on powder deposition techniques and the production of phosphor powders themselves. The text describes the necessary raw materials, flux materials, and growth conditions for producing ZnS powders. It provides a quantitative analysis on optimal processes and parameters for ensuring higher quality color and screen resolution. Offering a detailed guide for next-generation scientists and engineers in the field, Cathodoluminescence and Photoluminescence describes current technologies and promising developments for producing higher quality, energy-efficient, and long-lasting phosphor CR and flat CL screen displays.
