Description
Summary:In this study, zinc oxide (ZnO) nanocolloids (ZnONCs) were prepared in an electrical discharge machine using the electrical spark discharge method. ZnONCs comprising ZnO nanoparticles (ZnONPs) and zinc nanoparticles (ZnNPs) could be successfully prepared using metal electrodes with 99.97%-purity zinc (Zn) wire and deionized water as the dielectric fluid at normal temperature and pressure; chemical substances were not required in the preparation. According to the results of ultraviolet–visible spectroscopy, the ZnONP characteristic peak value was 345 nm. X-ray diffraction results indicated that ZnONCs had both Zn and ZnO crystallite orientations. Transmission electron microscopy results revealed that ZnONPs and ZnNPs exhibited elongated crystals measuring 30–50 nm, a ZnO d-spacing of 0.25 nm, and a Zn d-spacing of 0.21 nm. Raman and photoluminescence imaging results indicated favorable structural quality and crystallinity.
