Nanosized zinc (II) chromite (ZnCr2O4) is synthesized by low temperature (120 °C) sol gel auto combustionwith annealing temperature of 800 °C. X-ray diffraction (XRD) pattern confirm that the zinc chromite is in single phasecrystalline nature, which is further validated by Rietveld refinement analysis. Crystal structure was refined in cubic withspace group Fd3m. Particle size obtained from XRD is about 20 nm. Average grain size distribution ~ 50 nm in diameterwere found out by scanning electron microscopy (SEM) with Image-J software. The corresponding peaks of Zn, Cr and Owere observed in the energy dispersive analysis of chromites confirms the formation of ZnCr2O4. FTIR spectra showedtwo significant absorption bands, one around 621 cm-1 which is attributed to the intrinsic vibration of tetrahedral sitesand the other at 518 cm-1is due to octahedral sites corresponds to Cr – O stretching modes in ZnCr2O4. An infraredstudy also confirms the spinel nature of chromites.
