Abstract

The phonon Raman spectra of (Pb2Cu)Sr2Y1-xCaxCu 2O8+d (Pb3212), (Pb2Cu)Sr0.9La1.1CuO6+d (Pb3201), and (Pb0.5Cu0.5)Sr2YCu2O7+d (Pd1212) are investigated and phonon assignments compatible with the layer stacking sequences found in these Pb-based cuprate superconductors are proposed. In particular, the assignment of the 480- and 570-cm-1 phonons to oxygen in the PbO and SrO layers, respectively, is established. In the case of Pb3212 we find that the intensities of the CuO2-plane phonons decrease with increasing carrier concentration. This effect appears to be, at least partly, due to an interaction between the CuO2-plane phonons and Raman scattering associated with conduction carriers.
