Luminescence of semiconductors is nowadays based on very firm background of solid state physics. The purpose of this book is to introduce the reader to the study of the physical principles underlying inorganic semiconductor luminescence phenomena. It guides the reader starting from the very introductory definitions over luminescence of bulk semiconductors and finishing at the up-to-date luminescence spectroscopy of individual nanocrystals. The book thus set the aim of filling the gap between general textbooks on semiconductors and dedicated advanced monographs. At the beginning, important knowledge of the solid state like lattice vibrations, exciton–phonon interaction and the concept of configurational coordinate are reviewed. Self-contained chapters are then devoted to exciton luminescence processes, effects of high optical excitation, and to an overview of the essentials of electroluminescence. Apart from spontaneous luminescence, special attention is paid to stimulated emission and investigation of optical gain. Considerable space is given also to optical processes in low-dimensional semiconductor structures. The book has been written by experimentalists and is destined primarily for experimentalists, too. Visual approach using schemes and graphs is used frequently instead of rigorous mathematical derivation. The chapter devoted to experimental techniques of luminescence spectroscopy is rich in content. Whenever it makes sense, the accent is put on how to extract from the appearance of luminescence emission spectrum (shapes of emission lines, their behaviour with varying experimental parameters) as much information on microscopic origin of luminescence as possible. The book cannot be regarded as a comprehensive monograph on semiconductor luminescence; selected examples from extremely rich literature only have been chosen to illustrate the text
