Аннотация In this presentation we synthesized SnO2 thin film by sol-gel process. Starting from Tin(II) chloride as precursor and methanol as solvent the film was deposited on glass and quartz substrate by novel dip coating method. Structural and morphological analysis was carried out by X- Ray diffraction (XRD) mea-surement and Scanning electron microscopy (SEM). Optical characteristics were analyzed from the study of transmission spectrum data obtained by UV / VIS Spectrophotometer. It is observed that the transmission and grain size were more in case of quartz than glass substrate whereas the band gap was more in glass than quartz substrate. From XRD measurement it was confirmed the tetragonal structure of SnO2. EDS analysis depicts the weight percentage of Sn and O as 78.71 % and 21.29 % respectively and also confirms the purity of the film. From the study we concluded that the structural configuration changed a little with change in substrates at same conditions and quartz is the preferable substrate than glass.
