Abstract
We have synthesized Sn0.2Fex Cr1.8 – xO3 nano oxides with x= 0.0, 0.1, 0.2, 0.3. Single phase corundum structure and nanophase structure of the as-synthesized samples were confirmed by X-ray
diffraction (XRD) and by transmission electron microscope (TEM). Crystallite sizes were calculated using the Scherrer’s formula whilst particle sizes were obtained by TEM and found to be varying from 27.06 to 32.05 nm for the samples synthesized at different iron content. The optical measurements were performed by UV-visible spectroscopy. We observed that the band gaps and the refractive index vary with iron content.
