Nanocrystalline SnO₂ powder was successfully prepared by using simple sol-gel technique. The sol-gel 400 °C to obtain the SnO₂ nano-powder. The structural property of (SnO₂) nanocrystalline powder was investigated by using X-ray diffraction (XRD) technique. The optical properties were studied using Uv-Vis Spectroscopy, by recording the absorbance and transmittance spectra. The XRD pattern of the as-prepared sample demonstrated the formation of a rutile structure of SnO₂ nanocrystallites. The Scanning Electron Microscopic (SEM) analysis showed a homogeneous distribution of quite small grains over scanned area. The Uv-Vis absorbance spectra also showed a characteristic peak of absorbance at λ = 312 nm corresponding to SnO₂. The energy band gap measurement for nanocrystalline SnO₂ thin film was done from the graph of variation of ( αhƲ)² versus hƲ. The measured value of optical bandgap energies for SnO₂ thin film is 3,78 eV. The results show that the transmittance of the synthesized SnO₂ film is 78 % in the spectral range 350 nm to 800 nm.
