Abstract
The ZnO nanoparticles has unique properties like wide band gap energy, large excitation energy, acts as a functional material near UV emission, optical transparency [1]. It has versatile applications in optoelectronic devices, which creates the immense interest in its synthesis. Pure ZnO&Copper doped ZnO nanoparticles were prepared by Controlled Precipitation method. The structural characterization of the samples was investigated by X-ray diffraction and Scanning electron microscopy. The crystalline size of Pure ZnO nanoparticle is 22nm&Copper doped Nanoparticle is 11 nm is revealed by XRD. SEM micrographs reveals that both images are cluster shaped. The FT-IR showed that various functional groups have been formed. UV visible spectroscopy determines the band gap energy of ZnO nanoparticles.
