Structural and Morphological Study of Nickel Doped Tin Oxide Nanoparticles Synthesized Via Sol-Gel Technique

Abstract

In the present paper nickel doped tin oxide nanoparticles were synthesized by using simple sol–gel technique. The as-synthesized sample was characterized by means of X-ray powder diffraction (XRD) spectroscopy and Energy-dispersive X-ray spectroscopy (EDX) techniques for its structural analysis. XRD spectrum reveals that all the nanoparticles are highly polycrystalline in nature and five major peaks were clearly observed. Ni-doped SnO2 crystals existed mainly as tetragonal rutile structure. The average particle size of the nanoparticles was calculated by using the Scherrer formula and it was obtained 20 nm. EDX analysis confirms the presence of Nickel. No other impurities were found. The morphology of the nanoparticles was analyzed by using scanning electron microscope (SEM). The SEM image of the studied nanoparticles confirms the existence of very small, homogeneously distributed, spherical and crystalline nanoparticles.
