Abstract
Zinc oxide nanoparticles sample is prepared by the precipitation method. This method involves using zinc nitrate and urea in aqueous solution, then (AgNO3) Solution with different concentrations is added. The obtained precipitated compound is structurally characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FTIR). The average particle size of nanoparticles is around 28nm in pure, the average particle size reaches 26nm with adding AgNO3 (0.05g in100ml =0.002 M) (0.1g in100ml=0.0058M), AgNO3 (0.2g in 100ml=0.01M) was 25nm. The FTIR result shows the existence of -CO, -CO2, -OH, and -NO2- groups in sample and oxides (ZnO, Ag2O).and used an atomic force microscope and microscope scanning electron to model the record.

Summary
Zinc oxide is one of the semiconductor inorganic compounds with the formula ZnO. It usually appears as a white powder nearly insoluble in water, which is widely used as an additive into numerous materials and products including, paints, glass, cement, ceramics, rubber lubricants, plastics, ointments, adhesives, pigments, sealants, and foods batteries. Atoms are a few tenths of a nanometer in diameter and molecules are typically a few nanometers in size. Nanometer is a magical point on the length scale for this is the point where the smallest man-made devices meet the atoms and molecules of the natural world. Nano means 10-9, so a nanometer is one billionth of a meter and is the unit of length that is generally most appropriate for describing the size of single molecule.
