Microstructural, Optical and Morphological Studies of SnO₂ Nanoparticles Obtained by Sol-Gel Method

Tin oxide (SnO₂) nanoparticles were synthesized by the reaction of SnCl₄.5H₂O via sol-gel method using surfactant. Ammonia is added to neutralize pH in the sol-gel reaction. The samples were characterized by XRD analysis showed well crystallized tetragonal rutile SnO₂ can be obtained for the sample calcined at 400°C for 2 hrs. Optical studies of the samples were investigated by Fourier transform infrared spectroscopy. Surface morphology was studied using Scanning electron microscopy and Transmission electron microscopy. Our results suggest that the temperature plays an major rolefor the growth of nanoparticles.
