In this work, the effects of doping post transition metal (Pb2+) on the structural, morphological, elementaland optical properties of pure chromium oxide nanoparticles are reported. The structural andmorphological properties were examined by X-ray diffraction and scanning electron microscopy (SEM).The elemental composition of the prepared nanoparticles were estimated from energy dispersive X-ray(EDX) absorption spectra. The band gap energies of the prepared nanoparticles (4.72-3.78 eV) obtainedfrom UV-vis absorption spectroscopy is higher than that of bulk Cr2O3 (3.3 eV), which ensures that theprepared nanoparticles were successfully synthesized in the nano-region.
