In this research zinc oxide (ZnO) Nanostructures were grown using Carbothermal Reduction method on Si substrate with magnetron sputter deposited Nano sheet .The structural and morphology of ZnO nanostructures were studied by x- ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) . Photoluminescence and optical absorption were measured by UV excitation and UV-Vis-Near IR spectrophotometer.With the help of X-ray energy loss spectroscopy density was determined. Visible Luminescence was observed. Substrate temperature, deposition time and Cu Nano-sheet thickness affect nanostructure dimension and optical properties. The presence of copper increases the band gap of ZnO occurs as well as the spectrum would shift toward the red (Red Shift).x -Ray diffraction pattern show Vrtzayt hexagonal structure for zinc oxid structures
