Abstract
Owing to their use in fluorescent lamps and many display applications, luminescent materials affect our daily life. Improvement of already very mature as well as development of new materials demanded by a variety of new applications are the focus of research today. The latest advances in the field of electroluminescence enable new displays and light generation concepts that challenge the classical areas of application of luminescent materials.

While in the seventies and eighties the field of luminescent materials seemed to be fairly well covered, research in the nineties has been revitalized both in industry and academia. Improved performance of allegedly mature ªclassicalº materials has demonstrated impressively the role of until then often neglected parameters such as surface and particle properties. In a business as developed as the lamp market new lamp features such as reduced mercury consumption can lead to a competitive edge and new phosphor research programs. Quantum cutter phosphors that generate two visible photons from one UV photon are the focus of research again, for example, for plasma display panels as huge flat and thin hang-onthe-wall TVs. Promising new developments such as electroluminescent fullcolor displays or the blue (laser) diode have created excitement and numerous research efforts in laboratories around the world. The direct conversion of electricity into light, common to both applications, challenges current concepts and might eventually revolutionize the way we illuminate rooms, car lights, or traffic signals, and how we display video information. A deep understanding of the interaction of light and matter together with advanced material chemistry is the key to both improved and new lighting and display products.
