Micro-Raman spectra of erbium-doped Bi-2212 are reported. The assignment of the observed bands is made on the basis of the results of lattice dynamical calculations and known vibrational spectra of pure Bi-2212 and Y-123 systems. The characteristics of the observed bands seem to depend mainly on the
