2006-9-22 The average grain size of the ZnO nanoparticles is in the range of 24–40 nm, depending on the mechanical grinding time. The UV–vis diffuse reflectance spectrum of the ZnO nanoparticles indicates a band gap of about 3.3 eV with an onset of absorption at about 3.1 eV, showing a weak red shift compared to 3.37 eV for the bulk ZnO.
