The diffraction pattern for the sample synthesized using the acetate precursor, i.e., NNF-A, comprised of a single α-NaNdF4 phase (denoted with a diamond symbol). The NNF-C and NNF-N samples (synthesized using the chloride and nitrate precursors, respectively) had two phases corresponding to α-NaNdF4 and NdF3 (denoted with a solid square symbol) phases.
