Book Description
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.

Book Description
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.

Book Description
Cathodoluminescence is the basic phenomenon behind the function of cathode ray tubes. Thus a knowledge of its fundamentals and applications is a prerequisite for the production of CRTs. This comprehensive treatment of cathodoluminescence covers all aspects scientists and engineers need for their work in the field. They include penetration of electrons into crystals, excitation of activator ions by incident radiation, motion of mobile carriers in crystals, optimization of cathodoluminescence phosphors and application of phosphors to picture tubes.

Book Description
Luminescence, for example, as fluorescence, bioluminescence, and phosphorescence, can result from chemical changes, electrical energy, subatomic motions, reactions in crystals, or stimulation of an atomic system. This subject continues to have a major technological role for humankind in the form of applications such as organic and inorganic light emitters for flat panel and flexible displays such as plasma displays, LCD displays, and OLED displays. Luminescent Materials and Applications describes a wide range of materials and applications that are of current interest including organic light emitting materials and devices, inorganic light emitting diode materials and devices, down-conversion materials, nanomaterials, and powder and thin-film electroluminescent phosphor materials and devices. In addition, both the physics and the materials aspects of the field of solid-state luminescence are presented. Thus, the book may be used as a reference to gain an understanding of various types and mechanisms of luminescence and of the implementation of luminescence into practical devices. The book is aimed at postgraduate students (physicists, electrical engineers, chemical engineers, materials scientists, and engineers) and researchers in industry, for example, at lighting and display companies and academia involved in studying conduction in solids and electronic materials. It will also provide an excellent starting point for all scientists interested in luminescent materials. Finally it is hoped that this book will not only educate, but also stimulate further progress in this rapidly evolving field.
