Аннотация Tin oxide films (SnO2) are prepared by the spray pyrolysis technique at different temperatures. The XRD measurement confirm that the thin films grown by this technique have good crystalline tetragonal rutile structures. The observations by scanning electron microscopy indicate that polycrystalline SnO2 film surfaces were formed by pyramidal grains (200 nm 300 nm), The composition on the films was obtained by Auger electron spectroscopy (AES), which is identical to the analysis EDS. Characterization by UV-visible spectrophotometry of thin films showed that the films have an optical transmission above 80 % in the visible and the values of Eg were in the range 3.98-4.02 eV.
