此物质是六方相的LaF3,PDF 卡片为32-0483。刚开始涉及这方面,恳请各位高手指点。
From your xrd results, the sample seems to be ploycrystal not single crystal. So why don't you take the SAED photo(from low mag BF)?
I have two more questions and one suggestion.
1. How did you calculate the interplanar d spacing for each plane?
2. Why there is no scale bar in the ED pattern or any information about your operation conditions? If you know these informations, then you can calculated d values by camera constant method.
3. It is dangerous to index the pattern just by inspection with similar patterns.
Good luck
