I have substituted cerium metal ions (Ce3+) inside HA crystal lattice. How can I measure change in lattice parameters of HA unit cells after cerium ion substitution? Normally, we use . 1/d2 = (4/3){(h2 + hk + k2)/a2} + (l2/c2) equation to calculate a and c lattice parameters. In this equation, (hkl) and d values are required to calculate a and c values. There are several signature peaks of HA like (002), (210), (211), (112), (300), (202), (310), (222), (213) and (004). Each peak has different hkl and d values.
How can I calculate d value precisely for specific peak?
Should I calculate a and c values for all signatured peaks of HA.
It would be nice, if you guide me about it.
Thanks
i addition, please do XPS for these sample, will get some more information regarding your query
the best way to obtain precise and reliable lattice parameter would be perform a refinement of the XRD pattern, using either Rietveld (not fully necessary in your case) or LeBail (enough here) method.
