(a) HTXRD patterns collected with Mo Kα radiation for the purchased Ag2O powders. The colours represent the temperatures (°C) in the scale on the right. (b) DW parameters for Ag (grey) and O (red). (c) Ag–O correlation coefficients versus the pair distance r from RT to 210°C. (d) Ag–Ag correlation coefficients versus the pair distance r from RT to 210°C. (e) Lattice parameter of the cuprite Ag2O structure for all the temperatures measured. The lines connecting the symbols are guides to the eye only. |
