The present invention, the step of preparing the that thioacetamide solution of the thioacetamide in a solvent, and comprising the steps of uniformly dispersed by the addition of ZnO powder in the thioacetamide solution, the ZnO powder dispersed thioacetamide solution the contents in the oven, and by maintaining the temperature of the oven at 60~95 ℃ thioacetamide is presented as the sulfur ions from the hydrolysis reaction with the zinc ions of the ZnO powder to form a ZnS shell on the surface of the ZnO powder and, ZnO -ZnS core shell structure in which the ZnS shell is formed on the surface of the ZnO powder drying step and the precipitate that selectively separating the precipitated sediment, including the step of obtaining a nano powder is formed on the surface of the ZnS shell ZnO powder the present invention relates to nanopowder synthesis and thus a nano-powder of ZnO -ZnS core shell structure prepared by. According to the present invention, the ZnS is coated on ZnO powder surface forms a dense shell, it is possible to manufacture the nanostructured powder of ZnO -ZnS core shell structure with a high intensity light emission characteristics showing ultraviolet emission with high quantum efficiency.
