Abstract: A physical vapour condensation method is used to synthesise the nanoparticles of ZnO. The size of these nanoparticles varies from 40 nm to 100 nm. Mostly, these nanoparticles are spherical in shape but contain some impurities. The XRD data shows a sharp peak at 36.87°, which is very close to that of zinc oxide nanoparticles grown by oxidation in the presence of ambient gases i.e., oxygen mixed with argon. From UV visible spectra of these nanoparticles, a peak at 381 nm and 373 nm is observed. The broad peak at 373 nm is responsible for the conversion of zinc into zinc oxide.
