摘要：

LnRu(4)P(12) (Ln = La, Ce, Pr, Nd, Sm, Gd and Tb) with a filled skutterudite-type structure has been studied by using a micro-probed Raman scattering technique. Raman spectra have been observed and analyzed in terms of the phosphide-based filled skutterudite-type structure. The mode at around 380 cm(-1) is assigned to the motion of P atoms. Another mode at around 440 cm(-1) is related to the vibrations involving Ln atoms. Apart from CeRu2P12, the shifts of each mode are well scaled by cell volume or rare earth mass. This fact suggests that LnRu(4)P(12), not including CeRu4P12, are isostructural and have the same electric properties at room temperature. (C) 1998 Elsevier Science Ltd. All rights reserved.
