Ni-Doped SnO Nanoparticles S 2 ynthesized by Chemical Co-Precipitation Method

Ni-doped SnO2 nanocrystalline powders have been synthesized by the co-precipitation method from SnCl2.2H2O and NiCl2.6H2O. Nanoparticles crystallize in lower temperature (350°C) and shorter time (2hours) respect to other methods. The samples have been characterized by various advanced techniques such as, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Transmission electron microscopy (TEM) and Vibrating sample magnetometer (VSM). The X-ray diffraction reveals that all samples are pure rutile-type tetragonal phase and the average particles size was observed to vary from 32 nm to 24 nm as the nickel content was increased, The TEM images confirms the size of tin oxide particles in nanoscale and VSM measurements indicate that Ni-doped samples have superparamagnetic properties and they are single domain nanoparticles.
