Electroluminescence and Related Topics

Light may be generated by the direct action of an electric field on various solid materials by a number of different mechanisms (electroluminescence). Electric fields may also influence luminescence phenomena excited by various types of radiation (electrophotoluminescence). The varied phenomena which have been observed, and their dependence on the operating parameters, are reviewed and theoretical explanations are given where possible. Possible practical applications of electroluminescence and electro-photolutminescence are also discussed.
