Magnetic field effects on the optical and structure properties of Hydrothermal grown ZnO nanorods
碩士 === 國立成功大學 === 物理學系碩博士班 === 100 === In this research, we manufactured ZnO nanorods arrays by hydrothermal synthesis with external magnetic. First, 0.37g Znic nitrate hexahydrate as the source of Zn and 0.175g hexamethylenetetramine were mixed in 50ml DI water in the beaker. Next, the beaker toget...
