摘要：

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