Compositional behavior of Raman active phonons in Pb(Zr1-xTix)3 ceramics
Original language description
A systematic study of the Raman spectra of PZT ceramics has been performed in a broad temperature interval (10?600 K) and a broad Ti/Zr concentration range around the morphotropic phase boundary (x = 0.25?0.70). The number of the spectral components wasestimated by a standard fitting procedure with damped harmonic oscillators as well as by counting the number of peaks and shoulders with the help of a purposely designed mathematical analysis based on frequency derivatives of the Raman spectra. This lastmethod proves to be very useful to study Raman spectra of disordered materials. For the case of PZT, the comparison with the Raman modes of PbTiO3 allows to assign the phonon bands on both sides of the morphotropic phase boundary, and the crossover fromthe tetragonal to rhombohedral phase spectra is clearly visible. However there are no indications of a systematic splitting of the E-symmetry modes into monoclinic A?-A?? doublets in the morphotropic samples.
