Dear all,
I have done Ti doped ZnO EXAFS data analysis but I guess it is getting mixture structure at high concentration for example 55% Ti doped ZnO.Also I done linear combination fit , but at fitting space norm(E),ZnO weight is 0.779 and ZnTiO3 is 0.221 then I changed fitting space is chi(k) ZnO weight is getting 25.2 and ZnTiO3 is getting 74.8 and it is not same
Hi Guven, Wow that is amazing. Would you share your Athena project file with us? I believe that it is possible but I'm a bit surprised that the numbers flip so evenly. What happens when you increase the energy range on the xanes fit so that it includes more of the EXAFS features? And what happens when you decrease the k-range and lower the k-range so that it includes more of the xanes features? Look at the unique parts of the spectra that belong to each component in the xanes and chi spectra, that should help you see why the values are coming out the way that they are. Shelly like
at fitting space norm(E) why?
regards
