Zinc oxide (ZnO) nanoparticles (NPs)  has been synthesized by precipitation method using ammonia as precipitating agent and ZnCl₂. 4 H₂O as starting material. Syntsesised nanoparticles (NPs) have been characterized by using XRD (X-ray diffraction), TGA/DTA (Thermo Gravimetric Analysis), IR (Infrared Spectroscopy), magnetic measurement, surface area measurement, SEM(Scanning electron microscopy) and TEM Transmission electron microscopy). XRD studies show that zinc oxide was formed as ZnO and it has hexagonal structure. Magnetic measurements showed diamagnetic nature of synthesized zinc oxide NPs. Surface area of NPs zinc oxide was 4.3737 m²/g. The particle size of the synthesized zinc oxide was determined by TEM. TEM images show that the size of particles of ZnO varied from 27nm to 82nm with average crystallite size 50 nm.
