Hydrothermal method was used for the preparation of tin oxide nanoparticles in the presence of isoamyl alcohol as solvent for surface directing agent. The effect of varying concentration of precursor and solvent was studied while other parameter like time and temperature were kept constant throughout the experiments. The nanoparticles were characterized by X-ray Diffraction, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscope and Thermal Gravimetric analysis. Functional groups was confirmed by FTIR. Particle size was calculated by XRD analysis as well as TEM images while TGA...
