Abstract
Results of fluorescence XAFS measurements for Mn in SrS and Pb in CaS as well as the absorption spectra of MnS and PbS are reported. The evidence of the similarity of the local structure around Pb ions in CaS and that of pure PbS is clearly shown by the analysis of the XAFS spectra. However, the structure around Mn ions in SrS is considerably deformed and not similar with that of MnS. The results suggest that the local structure of the impurity ions is very much dependent on the difference of the size of impurity ions and that of the host ions.
