    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.
