A structural analysis concerning the incorporation of dysprosium into read more A- and/or B-sites of the lead titanate is shown.The two "boundary" refinements are presented, i.e., Dy2+ substitutes for Pb2+ (Dy3+ substitutes for Ti4+) and Dy3+ substitutes for Pb2+ (Dy3+ substitutes for Ti4+).

The results offer quantitative information about the incorporation into both crystallographic sites.The increase of Dy3+ fraction into B-site provides the increase of the Ti4+ atomic displacement along the color touch 7/97 [001] direction and the tetragonal distortion.
