(Na0.5K0.5)NbO3-LiNbO3 (LNKN) is a lead-free ceramics, reported to show the maximum piezoelectric property when the Li content is 6.0 mol%. The temperature dependence of the spectra was measured for LNKN in the 4.0-8.0 mol% range of Li content by using Raman scattering. The stretching and bending mode of NbO6 octahedron especially changed the form and/or frequency of the spectrum with increasing Li content from 5.0 to 6.0 mol%. The range of this composition is corresponding to the composition with the maximum piezoelectric property.
