摘要：

The Raman spectra of lanthanum-doped lead titanate at high pressure or high temperature reveal that the phase transition pressure or temperature shifts to a lower pressure or temperature with decreasing grain size. Mechanism of the shift of the phase transition point has been discussed by comparing with the changes of the tetragonality c/a, as a function of La concentration x and grain size.
