Abstract: Tin oxide nanoparticles have been prepared by conventional sol-gel technique. Tin chloride (SnCl2.2H2O) was used as tin and zinc sources. Ethylene glycol and alcohol were used as solvents under different synthesis conditions. Transparent SnO2 sol was prepared after continuous stirring and refluxing at 50oC. Thin films prepared from SnO2 sol have also been deposited on glass substrate by spin coating at 500 rpm for 15 seconds and then at 3000 rpm for 20 seconds. The morphological, compositional and structural properties of SnO2 nanoparticles were characterized by XRD, Scanning electron microscopy (SEM), FT-IR and UV-vis-IR absorption spectrum. X-ray diffraction (XRD) patterns show that the preferred orientation was (111) with orthorhombic crystal structure. Crystallite size was calculated to be ~30 nm from XRD results. Scanning electron microscopy (SEM) results show the formation of nanodiamonds (~ 40 nm) and nanorods (~30 nm) after annealing at 300oC for 60 minutes. It is important to mention here that the preparation of SnO2 nanostructures without the use of any surfactant and ligand during sol synthesis. Fourier Transform Infrared (FTIR) spectra give peaks due to resonance of vibration, stretching of atoms and bond between them.
