Book Description
Electroluminescence deals with the multiplicity of forms related to electroluminescence phenomena. The book reviews some basic observations of electroluminescence, the Gudden-Pohl and Dechene effects, the electroluminescence phenomena in zinc sulfide phosphors, in silicon carbide, and in compounds composed of elements in groups III and V of the Periodic Table (such as gallium phosphide). The text also explains polarization of free charge carriers, the outline of junction breakdown theory, carrier recombination, and phosphor suspensions. The book describes the growth of zinc sulfide crystals (from solution, melt, or vapor), electroluminescence effects in zinc sulfide crystals, and observations made in the pre-breakdown region in single crystals of cadmium sulfide. Boer and Kummel (1952) describes the pre-breakdown region, under stable and wholly reversible conditions, as being connected with thermal instability. The book notes that the reversibility and repeatability of the phenomena below the breakdown point show that the field effects responsible for the sharp increase in conductance do not damage the crystal. The text also discusses the construction and characteristics of electroluminescent cells, as well as their applications. The book will prove valuable for physico-chemists, technical designers, or engineers whose works are related to instrumentation and solid-state electronics.

Book Description
Reports on the progress in organic materials that can glow a number of different colors; may soon be used in a number of applications such as panel displays, backlights of liquid crystal displays, indicator lights, light sources for optical communication, watches, toys, and microwave ovens; and has already been used in a prototype of a 40-inch color plasma display panel. The topics include electron processes in organic electroluminescence, making polymer light-emitting diodes with polythiophenes, electroluminescence and photoluminescence in fullerenes, chelate metal complexes, white-light-emitting diodes, the growth and characterization of display devices using vacuum-deposited organic materials. and novel fabrication techniques for devices.

Book Description
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.

Book Description
Organic solids exhibit a wide range of electrical and related properties. They occur as crystals, glasses, polymers and thin films; they may be insulators, semiconductors, conductors or superconductors; and they may show luminescence, nonlinear optical response, and complex dynamical behaviour. The book provides a broad survey of this area, written by international experts, one third being drawn from Eastern Europe. Electrical, optical, spectroscopic and structural aspects are all treated in a way that gives an excellent introduction to current themes in this highly interdisciplinary and practically important area. The coverage is especially strong in the areas where electrical and optical properties overlap, such as photoconductivity, electroluminescence, electroabsorption, electro-optics and photorefraction.
