用溶液法在镀有ZnO缓冲层的硅衬底上制备出定向ZnO纳米杆阵列,然后再通过硫代乙酰胺(TAA)辅助硫化法将氧化锌一维纳米结构转化为ZnO/ZnS的核-壳纳米结构.运用X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和室温光致发光谱(PL)研究了样品的结构、形貌和光学性质.结果表明,ZnO/ZnS核-壳纳米杆的带边发光峰比ZnO纳米杆有显著增强,且峰位蓝移. ZnO nanorod arrays were prepared on silicon substrates coated with ZnO buffer by solution method and then converted into ZnO / ZnS core-shell nanostructures by TAA assisted sulfidation method. Shell nanostructures.The structure, morphology and optical properties of the samples were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and room temperature photoluminescence (PL) / ZnS core-shell nanorods with edge-band luminescence than ZnO nanorods significantly enhanced, and blue-shifted peak position.
