Sputtering Phenomena of ZnS Nanomaterial by Impacting of High-Energy Electron in a Transmission Electron Microscope
An interesting sputtering phenomenon was shown when ZnS nanomaterial was irradiated by high-energy beams in a transmission electron microscope (TEM). Almost sputtered nanoparticles were spherical and well-dispersed. The sizes of deposited ZnS nanoparticles showed a good gradient distribution based on their distance away from the sputtering target. These nanoparticles had gradual changes in diameter from about 1 to 15 nm. This research may afford a simple and efficient method to prepare well-dispersed semiconductor nanocrystals in a small size range.
