"BALL-MILLING TUNED BAND STRUCTURES OF ZnO NANOPARTICLES …

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. This was supported by FE-SEM images. Furthermore, it was found that the ball-milling created defects, resulting in a narrower energy gap (Eg).

Ball Milling - an overview | ScienceDirect Topics

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
