Research for a brighter future

Fraunhofer Application Center for Inorganic Phosphors

Light emitting diodes (LEDs) are the future of lighting technology. Modern high-power LEDs offer numerous advantages in terms of efficiency, compactness, lifetime and environmental protection as compared to conventional incandescent and energy-saving lamps. New challenges not only consist of improving the LED chips, but also in the phosphors and encapsulation materials. In addition to the efficiency of the LEDs and the phosphor, reliability and colour stability are also important aspects. The thermal management in LEDs and LED modules  is of crucial importance.

Rising demands in intelligent lighting systems, especially those which are particularly adapted to the respective needs of the user or application, are triggering great amount of interest in starting new research projects.

In the field of phosphors, our range of services consists of the evaluation, design, and development of phosphors and phosphor systems with the aim of improving their efficiency, reliability, and colour stability. In order to do so, we apply comprehensive optical and spectroscopic analyses, thermal and microstructural characterizations at the Fraunhofer Application Center in Soest as well as investigations into the long-term stability of light-emitting diodes and lighting elements.

The output of our research activities have led to phosphor-doped glasses and glass ceramics for lighting and lighting technology as well as medical diagnostics. Further research fields include the characterization of optics for light-emitting diodes as well as the microstructuring of optics and phosphors.
