Abstract

A controlled modification of the parameters of the zinc oxide band structure has been demonstrated using the methods and approaches of nanostructure engineering by varying the duration of high-energy mechanical grinding. It has been shown that an increase in the dispersion time increases the monodispersity of ultrafine ZnO powder particles. A decrease in the zinc oxide band gap with increasing grinding duration is established based on spectrophotometric investigations. A nonmonotonic time dependence of the top of the valence band, as well as a high-energy shift of the valence and conduction bands for all dispersion durations, are demonstrated using experimental X-ray photoelectron spectroscopy data.
