Abstract
Tin Oxide SnO2 thin films was prepared by using spray pyrolysis deposition technique, They have been deposited on glass substrates with thickness (100-150)nm and in the range of temperatures (400-450-500)0C were studied structure characteristics by using X-ray diffraction (XRD). It was found that all Thin films prepared was polycrystalline in the form tetragonal crystalline quadrant based system .The Optical properties has been studied using transmission spectra and it well found the highest value of optical transmission was 76% in rang (800-900)nm, Then study the effect of change thickness thin films and substrate temperature on the structural and optical properties. Show that the high temperature leads to the regularity of the crystal structure and increase thickness leads to an increase in the particle size, the visual permeability decreases up thickness but increases with high temperature deposition temperature
