| 摘 要： | 采用水热法制备了稀土铈（Ce）掺杂的ZnO纳米棒，并利用X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和光致发光谱（PL）对样品进行表征．结果表明：Ce成功的掺入到ZnO中，掺杂的ZnO纳米棒有较好的结晶质量，直径约为8nm．另外，随着Ce的掺入，紫外峰峰位发生红移，这是因为掺杂后带隙变窄，从而导致了紫外峰的红移．

| Abstract: | Ce-doped ZnO nanorods were synthesized by the hydrothermal method.The structure,morphologies and optical properties were characterized by means of X-ray powder diffraction(XRD),scan electron microscopy(SEM),transmission electron microscope(TEM) and photoluminesecence(PL).The results indicated that the Ce ions were successfully incorporated into ZnO,and the diameter of nanorods was about 8 nm.Photoluminescence measurements were also carried out,the result showed a red shift in violet emission with the Ce dop... |
