RT - Journal Article T1 - Synthesis of Sn 0.986 Ni 0.014 O Nanoparticles and Study of Their Optical Band Gap JF - ijop YR - 2012 JO - ijop VO - 6 IS - 2 UR - http://ijop.ir/article-1-120-en.html SP - 113 EP - 116 K1 - Nickel K1 - tin monoxide K1 - nanoparticles K1 - optical band gap AB - 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 Sn0.986Ni0.014O nanoparticles is 27 nm. UV-Vis spectroscopy is revealed the optical band gap to be 3.98 eV for Sn0.986Ni0.014O nanoparticles that is higher than the bulk value of SnO (2.5–3 eV).
