Hello everyone. I am writing to inquire whether Hf reference XAS data may be available to anyone. As I am working on one of my projects on Hf-doped CaF2 nanoparticles. I am currently looking for reference data that would support qualitative comparison and interpretation of the Hf edge spectra. In particular, I am seeking reference data for: Hf foil and HfO2 If reference data for Hf fluoride compounds are also available, those would also be very helpful. If anyone has such data and would be willing to share them, I would greatly appreciate it. Thank you.
