Thermoluminescence In Solids And Its Applications

McKeever gives us a comprehensive survey of thermoluminescence, an important, versatile, and widely used experimental technique. Bringing together previously isolated specialized approaches, he stresses the importance of the solid state aspects of the phenomenon. The book contains chapters on analysis and special properties, on instrumentation, and on the variety of defect reaction - using the alkali halides and SiO2 as examples - that can take place within a material to yield thermoluminescence. Three chapters concerning applications discuss the features of the solid state reactions to expain some of the properties observed in practice.

Thermoluminescence (TL) is a well-established technique widely used in do- metric and dating applications. Although several excellent reference books exist which document both the t- oretical and experimental aspects of TL, there is a general lack of books that deal withspeci?cnumericalandpracticalaspectsofanalyzingTLdata. Manytimesthe practicaldetailsofanalyzingnumericalTLglowcurvesandofapplyingtheoretical models are dif?cult to ?nd in the published literature. The purpose of this book is to provide a practical guide for both established researchers and for new graduate students entering the ?eld of TL and is intended to be used in conjunction with and as a practical supplement of standard textbooks in the ?eld.

Chapter2presentscomprehensiveexamplesofTLdataanalysisforglowcurves following ?rst-, second-, and general-order kinetics. Detailed analysis of num- ical data is presented by using a variety of methods found in the TL literature, with particular emphasis in the practical aspects and pitfalls that researchers may encounter. Special emphasis is placed on the need to use several different me- ods to analyze the same TL data, as well as on the necessity to analyze glow curves obtained under different experimental conditions. Unfortunately, the lit- ature contains many published papers that claim a speci?c kinetic order for a TL peak in a dosimetric material, based only on a peak shape analysis. It is hoped that the detailed examples provided in Chapter 2 will encourage more comprehensive studies of TL properties of materials, based on the simultaneous use of several different methods of analysis.

This volume provides the readers an in-depth, yet concise, overview of the physico-chemical structures, luminescence and related properties of II-VI compounds which are being utilised and exhaustively studied these days for their applications in LED's, modern optoelectronic devices, flat EL screens and panels, infrared detectors, photovoltaic and thermal solar energy converters etc. The book, therefore, should be useful to a wide variety of people (working in the field of luminescence and related properties of II-VI compounds, i.e. advanced graduate students) and serve as a review to researchers entering in this field and working on these materials. It should also be useful to solid state spectroscopists, lasers physicists; electronic and illuminating engineering people, and all those professionals using these materials.

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.

The focus of the book is to explore metal oxides exhibiting a high optical transmittance as applicable in the field of light-emitting diodes (LEDs), photo-catalysts, and so forth. It provides exposure to structural and chemical parameters of optically active metal oxides as a phosphor, innovative and 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 cells, VUV application, and long persistent light emission phenomenon. Features: 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.

This is the first book on the subject matter of relativistic nonlinear electrodynamics The book presents new results on various nonlinear electromagnetic phenomena The topics discussed in the book will be the center of fundamental research in the next decade
