Synthesis of Sn_0.986 Ni_0.014 O Nanoparticles and Study of Their Optical Band Gap

Sn_0.986 ni_0.014 o nanoparticles have been synthesized by a simple co-precipitation method. nanoparticles crystallize in lower temperature (350°c) and shorter time (2h) respect to other methods. the sample characterized by various standard techniques such as fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), atomic absorption spectroscopy (aas) and uv–vis spectroscopy. the x-ray diffraction reveals that sample is pure rutile-type tetragonal phase, the crystalline size sn_0.986 ni_0.014 o nanoparticles is 27 nm. uv-vis spectroscopy is revealed the optical band gap to be 3.98 ev for sn_0.986 ni_0.014 o nanoparticles that is higher than the bulk value of sno (2.5–3 ev).
