Professor Andries Meijerink (52) leads an active research group that focuses on the optical spectroscopy of lanthanide ions in solids and of semiconductor quantum dots. In the field of lanthanide ions his recent work involves fundamental research on finding new concepts also related to applications in solar cells, LEDs and scintillators. The research on quantum dots is aimed at unraveling the influence of quantum confinement and surface effects on the electronic structure of quantum dots through optical spectroscopy and using the quantum dots as labels in bio-imaging. For his research Andries Meijerink has received several awards, including the DSM Award for Chemistry and Technology (1989), the Shell Incentive Award (1995), the Gold Medal of the Royal Dutch Chemical Society (1999) and the Centennial Award for Luminescence and Display Materials from the Electrochemical Society (2002). In 2009 he was elected as a member of the Royal Netherlands Academy of Sciences.

In this capacity Morgan provides technical direction for DOE supported R&D, co-authors the DOE SSL Multi-Year Program Plan and Manufacturing Roadmaps, and monitors DOE supported R&D projects. Morgan has a Ph.D. in Materials Science from the University of California, Santa Barbara with an emphasis on electronic and photonic materials. At UCSB Morgan performed research on GaN micro-cavity LEDs, non-polar LEDs, laser diodes, VCSELS, and UV LEDs.
Dr. Madis Raukas received his degree in Physics from the University of Georgia in Athens, Georgia, where he studied different materials for their light emission efficiency and quenching criteria with Profs. Yen and Happek. He joined OSRAM SYLVANIA Central Research in Beverly Massachusetts in 1997 and has worked since on understanding and developing various optical materials for lighting applications, from fluorescent to LEDs and lasers. Dr. Raukas currently leads the Materials R&D group for Ceramics and Polymers at OSRAM Opto Semiconductors. His research interests cover different LED and LD materials aspects with a particular focus on novel light generation and conversion schemes. His work has helped produce more than 40 scientific publications as well as numerous patents and he has been among recipients of several technology development team awards both nationally and internationally.

Seminar: Designing luminescent materials
The purpose of this seminar is to discuss tools that can be used to design luminescent materials (phosphors and scintillators) with the goal of developing lighting and detector products with maximum efficacy and at minimum cost. Major topics that will be covered are the selection of host lattice and of the luminescent ion, the influence of chemical composition and crystal structure on the spectral attributes of the luminescent material. The seminar will also provide an overview of phosphors and scintillators that are of commercial importance.
