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).
