Luminescence science and display materials

Abstract

Luminescence is defined broadly as the generation of light in excess of that radiated thermally. Man's fascination with luminescence stems from when an otherwise invisible power is converted into visible light. The commercial importance of luminescence is ubiquitous, being manifest in lamps, displays, X-ray machines, etc. In ECS, the Luminescence and Display Materials (LDM) Division provides a forum for work on the physics and chemistry of light generation from electrical energy and the technology of the various light producing devices. Aspects of these areas are briefly described in the following sections.
