Effect of Co Doping in Tuning the Band Gap of LaFeO3

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 h...

Description
Summary:	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.
