Аннотация We report here a simple wet chemical process to synthesize ZnO nanoparticles. The morphology of the nanoparticles was observed in field emission scanning electron microscope. The nanoparticles have average diameter ~ 100 nm. The optical property of the synthesized ZnO nanoparticles was investigated using UV-visible absorption spectra. The synthesized nanoparticles exhibit strong absorption at ~ 279 nm. The band gap of the nanoparticles was calculated from the absorption spectrum and found to be 3.76 eV. Thus the synthesized ZnO nanoparticles will be useful in various optoelectronic applications.
