Synthesis of Novel Oxyhalides as Multifunctional Host Structures Professor Rob Green from Alabama State University will present a seminar. Synthesis of Novel Oxyhalides as Multifunctional Host Structures Abstract: A tetragonal oxyfluoride Ba2SrGaO4F, a novel material in the Sr3AlO4F family of materials, has been synthesized via solid-state method and exhibits self-activated photoluminescence (PL) under 254nm light after annealing in a reducing atmosphere of 4%H2/96% Ar. The structure of this material is determined by powder x-ray diffraction and confirmed using high-resolution neutron [...]
