摘要：

Raman-scattering spectra at room temperature and 10 K are studied for binary "unfilled" and lanthanide-filled skutterudite antimonides. In the binary skuttertudites IrSb3 and RhSb3 all eight Raman-active vibrational modes have been identified while seven of the eight modes have been identified in CoSb3. In the case of the filled skutterudites these vibrational modes are sensitive to the lanthanide "filler" ions which produce a shift and large broadening of the vibrational modes. Polarization measurements on these polycrystalline samples were used to identify the A(g) modes. The experimental data are compared to theoretical predictions. [S0163-1829(99)04309-X].
