Figure 4

(a) Raman spectra of KN-Pt and KN-NL. The insets show the schematic illustrations of bending and stretching vibrational modes of NbO6 octahedra. (b) IR reflectance spectra of KN-Pt at room temperature. (c) Temperature dependent IR reflectance spectra of KN-Pt. The rectangular area corresponds to the obvious changes of IR modes. (d) Comparison of Raman and IR active modes for KN-NL and KN-Pt with the proposed assignment.
