摘      要：A structural analysis concerning the incorporation of dysprosium into A-and/or B-sites of the lead titanate is *** twoboundaryrefinements are presented,i.e.,Dy^(2+)substitutes for Pb^(2+)(Dy^(3+)substitutes for Ti^(4+))and Dy^(3+)substitutes for Pb^(2+)(Dy^(3+)substitutes for Ti^(4+)).The results offer quantitative information about the incorporation into both crystallographic *** increase of Dy^(3+)fraction into B-site provides the increase of the Ti^(4+)atomic displacement along the[001]direction and the tetragonal distortion.
