In the present paper we reports the synthesis of spinel Maganese Chromites (MnCr2O4) Nano-Crystalline by sol gel method. The sample was calcined at different temperature like 750?C and 950?C for good results. Ethylene glycol which is used to control the agglomeration of Nano-particles. By powder x-ray diffraction combine average particle size of Nano-particles was determined which shows that crystal size increases from 19nm to more when we increase the sintered temperature. SEM shows that results are in good agreements. From PL spectra the band gap energy was calculated which is almost 4.03 eV at 750?C but it can decreases when we increase the temperature like 950?C is 3.89 eV. Raman results showed that wavelength is maximum like 1306cm-1 and 1465cm-1.
