Abstract
In this study, the synthesis of Tin (IV) Oxide nanoparticles was investigated. Primarily two different methods were examined for the synthesis of SnO2 nanoparticles. In chemical method, different amounts of CTAB were used. In green method, different amounts of Chamaemelum nobile extract were used. SnCl2.2H2O salt was used in order to the preparation of SnO2 nanoparticles. The morphology and the particle size of SnO2 nanoparticles were investigated by using Field Emission Scanning Electron Microscopy (FESEM), Transmission Electron Microscopy (TEM), Photoluminescence (PL), X-ray Diffraction (XRD), Energy Dispersive XRay Spectroscopy (EDS) and Fourier Transform-Infrared Spectrophotometer (FTIR). According to the X-ray diffraction analysis, the average crystallite size of Nps was in the range of 7-16 nm. Scanning electron microscope images showed the desired shape of tetragonal for the nanoparticles which was the most favorable structure for biological testing. Finally the biological properties of nanoparticles was discussed.
