英文摘要 | Raman scattering measurements of K2Sr(MoO4)(2) were performed in the temperature range of 25-750 degrees C. The Raman spectrum of the low-temperature phase alpha-K2Sr(MoO4)(2) that was obtained by first-principle calculations indicated that the Raman bands in the wavenumber region of 250-500 cm(-1) are related to Mo-O bending vibrations in MoO4 tetrahedra, while the Raman bands in the wavenumber region of 650-950 cm(-1)are attributed to stretching vibrations of Mo-O bonds. The temperature-dependent Raman spectra reveal that K2Sr(MoO4)(2) exhibits two sets of modifications in the Raman spectra at similar to 150 degrees C and similar to 475 degrees C, attributed to structural phase transitions. The large change of the Raman spectra in the temperature range of 150 degrees C to 475 degrees C suggests structural instability of the medium-temperature phase beta-K2Sr(MoO4)(2). |
