Figure 2
TEM images and HR-TEM results of U-doped NZO samples. Panels (a, e) refer to the NZO samples; (b, f), (c, g), (d, h) refer to the A−0.1, A−0.2 and A−0.4 samples, respectively; and (i, l), (j, m) and (k, n) refer to the B−0.1, B−0.2 and B−0.4 samples, respectively; additionally, the illustration shows the corresponding SAED result. |
