Structures and compositions of CsP-2 after heating at 900°C. (a) STEM-ADF image of CsP-2. (b) Enlarged view of the white square in (a). (c) Electron diffraction pattern acquired from the rim of CsP-2, in which many tiny bright spots exist in the STEM-ADF image. The inset shows the calculated Debye-Scherrer pattern of franklinite (ZnFe2O4). (d) Element maps of the same frame as (b). (e) EDS spectra acquired from the center and rim of CsP-2. The peak intensity is normalized for quantitative comparison.
