In this article single and double nozzle (SN, DN) chemical spray pyrolysis techniques(CSP) proved that tin dioxide SnO
2 thin film can be fabricated with different structures. SnO2 prepared from three different salts of tin with a concentration of 0.05 M, with thicknesses were about 0.2 ±0.02 µm. Microstructures inspections were achieved on films, beside optical transparency addition to the contact angle CA. The results show that films have tetragonal crystalline with different microstructures, from sheet to rod and flower-like aggregates, by the variation of the used salts by DN more than SN, also the value of the CA of the prepared films varies with different structures, reaching its highest value for flower-like aggregates of about 130°. Finally, the optical transparency was different corresponding to the disparity in surfaces roughness and topography. [ABSTRACT FROM AUTHOR]- Published
