Download or read book Unraveling Thermoluminescence written by C M Sunta and published by Springer. This book was released on 2014-07-15 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is essentially about the theoretical aspects of thermoluminescence (TL). It is structured and written in a manner which will specially be of interest to the fresh undergraduate students and young researchers planning to take up work in the field of thermoluminescence. It is arranged into seven chapters, starting with the historical growth of the subject of TL and an overview of the luminescence phenomena. A Physical model involving thermally disconnected deep traps is specially described. Using this model expressions are derived for the TL intensity growth curve, the supralinearity factor and the pre-dose sensitization factor. A new factor, called the sensitization factor is introduced which co-relates the supralinearity and the pre-dose sensitization factors. Dealing with the theoretical models of TL, limitations of the general order (GO) kinetics and the mixed order kinetics models are specially brought out. Due to the lacunae of GO model the determination of activation energy becomes subject to error, when GO model is applied to the experimental TL glow curves. Satisfying the quasi-equilibrium (QE) condition is essential for the validity of analytical models of TL. A new method is given to ascertain if QE condition is satisfied in an experimental glow curve. The book assumes a basic knowledge of physics and mathematics at an undergraduate level and takes the reader to the results at the cutting edge of understanding of the subject in an easy to understand manner.

It is a simple life which has achieved what it has, not with sudden luck or prosperity, but slowly and surely one step at a time.
Download or read book Theory Of Thermoluminescence And Related Phenomena written by Reuven Chen and published by World Scientific. This book was released on 1997-09-05 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2019-03-06 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, international leading experts in the study of thermally and optically stimulated luminescence give an up-to-date, comprehensive coverage of the theoretical and experimental aspects of these subjects, as well as their applications.The theory of thermoluminescence (TL) and optically stimulated luminescence (OSL) are discussed in detail including mainly solid state models of localized and delocalized transitions. These models cover the effects occurring during the excitation by irradiation and the read-out by heating or by exposure to light. The methods described consist of analytical mathematical considerations as well as numerical simulations.The main application of these effects, namely radiation dosimetry, includes personal and environmental dosimetry, as well as retrospective dosimetry and the dosimetry of cosmic radiation and space missions. Also discussed in detail are archaeological and geological dating, the use of luminescence dosimetry in medical physics as well as general applications in geosciences, other model subjects such as time-resolved luminescence and thermally assisted OSL, and the sister-subject of thermoluminescence in photosynthetic materials.

This book was released on 2013-03-09 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: All existing introductory reviews of mineralogy are written accord ing to the same algorithm, sometimes called the "Dana System of Mineralogy". Even modern advanced handbooks, which are cer tainly necessary, include basic data on minerals and are essentially descriptive. When basic information on the chemistry, structure, optical and physical properties, distinguished features and para genesis of 200-400 minerals is presented, then there is practically no further space available to include new ideas and concepts based on recent mineral studies. A possible solution to this dilemma would be to present a book beginning where introductory textbooks end for those already famil iar with the elementary concepts. Such a volume would be tailored to specialists in all fields of science and industry, interested in the most recent results in mineralogy. This approach may be called Advanced Mineralogy. Here, an attempt has been made to survey the current possibilities and aims in mineral mater investigations, including the main characteristics of all the methods, the most important problems and topics of mineralogy, and related studies. The individual volumes are composed of short, condensed chap ters. Each chapter presents in a complete, albeit condensed, form specific problems, methods, theories, and directions of investigations, and estimates their importance and strategic position in science and industry.
