In this work, we report a detailed temperature dependent inelastic light scattering study on a solid electrolyte LiZr1.9Al0.1(PO4)3 as a function of temperature, from 20 °C to 400 °C, in a wide spectral range of 60 - 1250 cm-1. We observed a clear signature of structural phase transition around ∼ 220 °C marked by the renormalization of the phonon frequencies and integrated intensity. The phonon modes frequencies above the transition temperature showed nearly temperature independent behaviour reflecting the disordered nature of the phase transition.
