    The latest research was based on the developing of new materials based on transparent conductor oxides (TCOs) used in several applications as environmental protection and detection. The nanostructures of metal oxides such as SnO2, ZnO, CuO and NiO are widely used in various optoelectronic devices such as photocatalysis, photodiodes, gas sensors and solar cells. SnO2 is a very unique material with its important properties such as low operating properties, high thermal stability, and a high degree of transparency in the visible region of the spectrum. Also, this material shows good antibacterial properties. For obtaining desirable properties of the synthesized nanoparticles, controlled synthesis and synthesis method play an important role such as preparation conditions and doped elements. The principal aim of this work programmed for realizing this thesis is synthesis and characterization of un-doped, doped and co-doped SnO2 thin films by spray pyrolysis method, using Co and Fe as doped elements. In this work, the candidate will be required to carry out scientific experiments for the preparation and characterization of prepared samples, Also some applications will be realized.
