Sažetak
The phonon-Raman spectrum of Bi_(2-x)Pb_xSr_2Ca_(n-1)Cu_nO_(2n+4+delta) had been studied in detail. The 630 cm^-1 phonon which is assigned as a z-vibration of the oxygen between the CuO_2 and the BiO layers, and of the oxygens of the BiO layers shows a sample dependent shoulder at 650 cm^-1. This shoulder is interpreted as a mode arising from different oxygen ordering in the BiO layers and from excess oxygen. Substituting Bi with Pb increases the amount of 2223 phase and the intensity of that shoulder decreases.
