【讨论】请大家看看这张电子衍射图

不太懂你做的材料，你可以试图标定一下，点拉长说明里面有大量纳米晶存在。

感谢楼上的。
我做的是化学成分比较复杂，有序性又不太好的蒙脱石。

The SAED pattern shows a pattern from a large grain with defect structures,since the feature of a spot pattern is just like that. If there are lots of nanocrystallins, the pattern might be a ring pattern.

No nanocrystalline at all! just grains with low angle grain boundry

off-axis twinned structure
