Abstract: The effects of particle size on the Raman spectra of ultrafine lead titanate (PbTiO3) particles are reported in this paper. Samples with different particles sizes were prepared by the sol-gel process using different calcination temperatures. The size of the particles was determined by X-ray diffraction with the aid of Scherrer's equation, and the vibration modes were studied at room temperature by Raman scattering. The Raman peaks exhibit downshift in frequency, broadening and intensity changes with decreasing particle size.
