Compared with the vibrational spectrum of SBN and KNSBN crystals, we can see that the influence of the Li ion in the C site in the KLN on the characteristic Raman and IR reflectivity spectra of the Nb O octahedron ion is very striking. Specially, the symmetric bend vibration mode υ 5 was split into three Raman lines, and the antisymmetric stretch and bend vibration modes υ 3 and υ 4 were all broadened greatly.
