Abstract
The Raman spectra for PbTiO3 of various grain sizes at different hydro static pressures have revealed that the soft E(1TO) phonon mode appear s to undergo a red shift in frequency and increases in linewidth with decreasing grain size, and that the pressure dependences of the soft m ode in nanocrystalline PbTiO3 can be correlated with the diffuse phase transition.
