Abstract

In the present study doped and undoped SnO2 nanostructures through Sol-gel method.. Prepared samples were characterized by advanced techniques for example scanning electron microscopy (SEM), X-ray diffraction (XRD) and Ultraviolet–visible near infrared spectrophotometry. X-ray diffraction (XRD) patterns have revealed that prepared doped and undoped SnO2 nanoparticles have rutile tetragonal structure nature. Average crystal size undoped SnO2 nanoparticles is calculated almost 33.5 nm and for cobalt, nickel and magnesium doped sample is 14.95 nm, 16.83 nm and 13.33 nm respectively. Band gap of un-doped SnO2 nano-particle is determined to be 3.76 eV. Though, band gap of doped samples are decreased. For Mg doped, Ni doped and Co doped SnO2 nano-particle band gap are determined to be 3.66, 3.58 and 3.49eV.
