Description
Summary:We present here the results of the Raman study of lattice dynamics and local compositional fluctuations in cubic spinel Zn2TiO4nanostructures. The observed Raman modes of the spinel structure are identified and attributed to local vibrational modes. Additionally, the analysis of the nonpolar E2(H) (∼437 cm-1, 54.2 meV) and A1g(∼716 cm-1, 88.7 meV) modes are made and contributed to lattice deformation associated with the distinct coordination preferences of Zn and Ti.
