Zinc sulfide (ZnS) and zinc oxide (ZnO) nanocrystals (NCs) were synthesized to arrangement the ZnS / ZnO core / shell NCs via chemical reaction afterward produced from nanocomposite. The modified development of ZnS / ZnO NCs and the sulfurization and oxidation ecosystems could detect many external appearance and colors. Photoluminescence (PL) was analyzed to determine the properties and optical features of such nanostructures, as well as the energy gap between chemical bands. In addition, material characterizations verified, take in electron microscopy scanning and X-ray diffraction a first rising ZnS/ZnO core / shell nanocrystals. An absorption spectrum of ZnO shells on ZnS cores NCs was limited to development technique. The prepared nanocomposites seemed to have the results of scanning electron microscopy (SEM) and uniform in size limited within 3-4 nm radius. The core / shell nanocomposites ZnS / ZnO NCs are capable of generating white light uses. The white light emission was accomplished by illumination the UV-LED (GaN) nanocomposites of the core ZnS and ZnO cover NC.
