A distinctive novel ZnO/ZnS core-shell structure on silicon was reported in this study. Compared with previous studies, ZnO nanorods encapsulated by 5 nm ZnS nanograins were observed using a scanning electron microscope. Furthermore, strong (111) cubic ZnS crystalline structures were confirmed using high resolution transmission electron microscopy, selected area diffraction, and X-ray diffraction. The optical properties changed and the antibacterial behaviors were suppressed as the ZnS shells were attached onto the ZnO nanorods. Moreover, the results also indicate that the hydrophobicity could be enhanced as more ZnS nanograins were wrapped onto the ZnO nanorods. The ZnO/ZnS core-shell structures in this research show promise for use in future optoelectronic and biomedical applications.
本研究报道了一种在硅上独特的新型ZnO/ZnS核壳结构。与先前的研究相比，使用扫描电子显微镜观察到由5 nm ZnS纳米颗粒包裹的ZnO纳米棒。此外，利用高分辨率透射电子显微镜、选区衍射和X射线衍射证实了强（111）立方ZnS晶体结构。当ZnS壳附着在ZnO纳米棒上时，光学性质发生变化，抗菌行为受到抑制。此外，结果还表明，随着更多的ZnS纳米颗粒包裹在ZnO纳米棒上，疏水性可以增强。本研究中的ZnO/ZnS核壳结构在未来的光电子和生物医学应用中显示出应用前景。
