During the synthesis of zinc oxide (ZnO) nanoparticles and nano-structures using an RF inductively-coupled thermal plasma system, it was found that ZnO nanoparticles synthesized in high enthalpy plasmas exhibit high purity and extremely small crystalline characteristics, with a size distribution suitable for various applications. The morphology of the ZnO nanoparticles was found to be influenced by process parameters such as chamber pressure, cooling method, and reactor configuration. Additionally, flower-like ZnO nano-structures consisting of hexagonal nano-rods with six facets were obtained by controlling operational parameters, showing good optical properties in photoluminescence analysis.
Zinc oxide (ZnO) nanoparticles and nano-structures were synthesized using RF inductively-coupled thermal plasma system. The ZnO nanoparticles synthesized in high enthalpy plasmas showed high purity and extremely small crystalline characteristics with the (30?50) nm size distribution applicable in various areas. The resultant morphology of the ZnO nanoparticles was influenced by process parameters such as chamber pressure, a cooling method and a reactor configuration. Thus, the effects of process conditions were discussed with perspective of the re-crystallization. In addition, by controlling the operational parameters, flower-like shaped ZnO nano-structures consisting of many hexagonal nano-rods with six facets were also obtained. The ZnO nano-structures showed a good optical property in photoluminescence analysis.
