Luminescence Of Inorganic Solids

Luminescence of Solids gathers together much of the latest work on luminescent inorganic materials and new physical phenomena. The volume includes chapters covering -- the achievements that have led to the establishment of the fundamental laws of luminescence -- light sources, light-dispersing elements, detectors, and other experimental techniques -- models and mechanisms -- materials preparation, and -- future trends. This international collection of cutting-edge luminescence research is complemented by over 170 illustrations that bring to life the text's many vital concepts.

These proceedings report the lectures and seminars of a course entitled "Luminescence of Inorganic Solids," held at Erice, Italy, June 15-30, 1977. This course \'7aS an activity of the International School of Atomic and No1ecu1ar Spectroscopy of the "Ettore Hajorana" Centre for Scientific Culture. The course opened with an overvievl of the present status of luminescence research and with an assessment of its future trends. The following lectures introduced the basic formalism behind the interaction of matter with the radiation field and the lattice phonons. The luminescence properties of various classes of in organic materials were treated next, for the specific cases of unfilled-shell activators (transition metal, lanthanide and actinide ions) and filled-s~e11 activators (s2 and d10 ions). Different models suitable for the description of the luminescence properties of semiconductors vlere examined next. The dynamics of energy transfer and relaxation in the excited state of t;1e activators were treated in lectures devoted to the luminescence phenomena of sensitization, concentration quenching and thermal quenching. Finally, the relevance of luminescence studies to the field of phosphor technology and to the laser field Has examined. Each lecturer began the treatment of this topic(s) at a fundamental level and finally reached the current level of research. The sequence of the lectures was determined by the requirements of a didactical presentation. The emphasis of the course was primarily on basic principles. The formal lectures Here complemented by seminars and discussions.

Microcharacterization of materials is a rapidly advancing field. Among the many electron and ion probe techniques, the cathodoluminescence mode of an electron probe instrument has reached a certain maturity, which is reflected by an increas ing number of publications in this field. The rapid rate of progress in applications of cathodoluminescence techniques in characterizing inorganic solids has been especially noticeable in recent years. The main purpose of the book is to outline the applications of cath odoluminescence techniques in the assessment of optical and electronic proper ties of inorganic solids, such as semiconductors, phosphors, ceramics, and min erals. The assessment provides, for example, information on impurity levels derived from cathodoluminescence spectroscopy, analysis of dopant concentra tions at a level that, in some cases, is several orders of magnitude lower than that attainable by x-ray microanalysis, the mapping of defects, and the determination of carrier lifetimes and the charge carrier capture cross sections of impurities. In order to make the book self-contained, some basic concepts of solid-state phys ics, as well as various cathodoluminescence techniques and the processes leading to luminescence phenomena in inorganic solids, are also described. We hope that this book will be useful to both scientists and graduate students interested in microcharacterization of inorganic solids. This book, however, was not intended as a definitive account of cathodoluminescence analysis of in organic solids. In considering the results presented here, readers should re member that many materials have properties that vary widely as a function of preparation conditions.

This practical guide to spectroscopy and inorganic materials meets the demand from academia and the science community for an introductory text that introduces the different optical spectroscopic techniques, used in many laboratories, for material characterisation. Treats the most basic aspects to be introduced into the field of optical spectroscopy of inorganic materials, enabling a student to interpret simple optical (absorption, reflectivity, emission and scattering) spectra Contains simple, illustrative examples and solved exercises Covers the theory, instrumentation and applications of spectroscopy for the characterisation of inorganic materials, including lasers, phosphors and optical materials such as photonics This is an ideal beginner’s guide for students with some previous knowledge in quantum mechanics and optics, as well as a reference source for professionals or researchers in materials science, especially the growing field of optical materials.
