dc.description.abstractA 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 254 nm 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 powder diffraction, which reveals similarities to Sr3AlO4F-type oxyfluorides and Ba2GaLaO5. Analysis of the refined Ba2SrGaO4F structure at room temperature reveals subtle changes in the polyhedral sub-units between the reductively annealed and air-annealed samples, which are correlated with the PL emission. © 2019 Elsevier Inc.en_AU
