| Summary: | We present here the results of the Raman study of lattice dynamics and local compositional fluctuations in cubic spinel Zn 2 TiO 4 nanostructures. The observed Raman modes of the spinel structure are identified and attributed to local vibrational modes. Additionally, the analysis of the nonpolar E 2 (H) (∼437 cm -1 , 54.2 meV) and A 1g (∼716 cm -1 , 88.7 meV) modes are made and contributed to lattice deformation associated with the distinct coordination preferences of Zn and Ti.
