Synchrotron X-ray diffraction patterns acquired at 30 keV allowed to determine both long- and shortrange ordered structures by Rietveld and pair distribution function (PDF) analyses, respectively. PDF examination of the as-synthesized sample allowed to discern a slight deviation from the basic cubic building unit because the Y−F bond lengths could be explained in S.G. I4/mmm with cell parameters a = 8.1520(9) Å and c = 11.5876(29) Å, whereas Rietveld analysis could equally well fit both the cubic and tetragonal descriptions for the heat-treated specimens. Also, PDF revealed that the as-synthesized sample exhibited less structural coherence than the heattreated one.5128-5136closedAccessdoped materialsnanoparticlesx-ray diffractionnanocrystalssynchrotronsArtigo de periódico080210.1021/acsomega.7b00668https://orcid.org/0000-0001-7707-7821
