Raman spectra of polycrystalline solids; application to the PbTi1-xZrxO3 system
Abstract
It is shown that Raman scattering from polycrystalline piezoelectric solids contains all of the essential features of Raman single-crystal spectra even when the crystal spectrum is quite anisotropic. As an illustration of the Raman powder technique, the ceramic ferroelectric-antiferroelectric system PbTiO3-PbZrO3 has been investigated and the "soft" E(TO) optical phonon modes measured in the tetragonal ferroelectric region. © 1970 The American Physical Society.
