Figure 2
Secondary electron image, taken on a scanning electron microscope (SEM), showing the typical morphology of the Ag3Sc2(PO4)3 crystals, which were obtained from a flux-grown Na3Sc2(PO4)3 material via ion exchange. EDX spot analyses and mapping on the surface and on cross sections of some selected crystals (cut in the middle and cutting faces analysed) yield no indications of Na+, but rather a homogenous distribution of Ag+ on and throughout the crystals. Details of these measurements are reported in Ladenstein et al. (2020). |
