Sol gel processed Pb1-xMx TiO3 (PMTx ; M = Co, 0≤ x≤ 0.3; Cu, 0≤ x ≤0.2) powders, calcined at 700°C, were characterized by X-Ray Diffraction (XRD) and Raman spectroscopy. XRD analysis revealed well resolved spectra, and we have followed the influence of addition of Co and Cu with Raman spectroscopy. Indeed, the results showed that solubility limit is reached at the concentration of 10% for the samples PCuTx , and that the structure of the samples is not significantly altered by incorporation of Cu, while addition of Co transforms it from tetragonal to pseudocubic. Moreover, Raman analysis shows that Co occupied both A (Pb) and B (Ti) sites of the ABO3 (PbTiO3 ) perovskite structure of these materials for x > 10 %, while Cu occupies the same site A (Pb) in the whole range of concentration. To our knowledge, effects of doping with Co and Cu elements and the study of sites occupation in such materials have not been reported.
