In the present work, we report, for the first time, the production of nanostructured ZnO thin films using green synthesized (GS) ZnO nanoparticles (NPs) by spray pyrolysis system. The effects of the deposition amount on the optical, electrical and structural properties of the ZnO thin films were investigated. The ZnO-NPs were synthesized using a Zn(Ac)(2)center dot 2H(2)O solution in an aqueous extract of Citrus reticulata peel. The morphologies of the GS samples were characterized by FE-SEM and the crystal structures were identified by XRD analysis. As the deposition amount increased from 5 to 20 mg the average crystallite size increased from 44 to 81 nm. The deposition amount and deposition time significantly affected the crystal type end size. The UV-evisible spectrum showed that the average optical transparency was higher than 85%. The electrical conductivity values significant changed with the crystal quality and morphology.
