BALL-MILLING TUNED BAND STRUCTURES OF ZnO …

In this research, high energy ball milling, which is a possible technique to narrow the band gap, was employed to tune band structure of ZnO. The ball-milled particles were evaluated by XRD, FE-SEM, UV-Vis, and EIS measurements. XRD measurements showed that the average particle size of ZnO nanoparticles was significantly decreased by ball milling.
