Herein, we reported the effect of cobalt (Co) doping on the optical band gap of LaFeO3 (LFO). The Co doped nanoparticles were prepared by a simple sol-gel technique with composition LaFe1–xCoxO3by varying content ratio of x = 0, 0.4, 0.5 and 0.6. Structure of the LFO and Co doped LFO nanoparticles have been investigated by X-ray diffraction (XRD) pattern. Whereas, surface morphology of LFO and Co doped LFO has been ascertained by scanning electron microscopy (SEM). The observed optical properties investigated by UV-Vis spectroscopy suggest decrease in band gap with Co doping in LFO, which can be useful for optoelectronic applications.
