Summary:In this work, the preparation of ZnO and ZnO: TiO2 thin films were conducted on glass prepared by sol-gel spray-spin coating technique. The performance and properties of nanostructured ZnO and ZnO: TiO2 thin films at different thickness were investigated. The effect of thickness on the electrical properties and optical properties have been characterized by using 2-point probe KEITHLEY 2400 source meter and UV-Vis spectrophotometer respectively. From the current-voltage measurement it shows the conductivity of nanocomposite ZnO: TiO2 was higher compare to nanostructure ZnO. The structural properties reveal the surface morphology of nanocomposite ZnO: TiO2 exhibit high surface area as the thickness of thin films increase. The optical properties show the band gap for nanocomposite ZnO: TiO2 decreases as the thickness increase.
