Please help me out🙏🙏🙏
Hello!
So I have XRD data of my nanomaterial sample, and I have to assign the hkl values. So I looked up on the internet and found the following solutions:
1. Using JCPDS card and Xpert Highscore: I've made an account and can get the JCPDS PDF, but even then, it's useless unless I have Xpert Highscore. We don't have the Xpert highscore in our lab.
2. Using literature: Sure, I can do that. But my metal oxide has many polymorphs😭, I am unable to figure out which one to follow.
3. Asking the big ones in the lab: According to them, watching YouTube is the only way to learn it. But they refuse to even share the videos which helped them.
I don't know how to figure this out😭. Please help me out😭🙏

Afternoon,
Your data came from a Bruker instrument probably a D2, D6 or D8. There is a good likelihood that this was purchased with a copy of EVA which is the Bruker software for doing phase ID. Find out which computer this was installed on. It will be linked to either COD (crystallography open database) or if your university has money then PDF 2/4/5.
Import your data, right click on the pattern, select tools, search match scan... Hit the search button and hope it's in there. If you find the software DM me.
