摘要: 采用化学气相沉积法,在没有采用任何催化剂的条件下,在Si(100)衬底上成功制备出Sb掺杂大尺寸ZnO纳米棒,并对样品进行了结构和光学性质的表征。结果表明:纳米棒为结晶质量较好的六角纤锌矿结构,在能量色散谱(EDS)中观测到了Sb元素的存在。此外,在低温光致发光(PL)光谱中还观测到了与Sb掺杂相关的中性受主束缚激子发光峰(A0X)、自由电子到受主能级跃迁的发光峰(FA)、施主受主对(DAP)以及DAP的一级纵向光声子伴线(DAP-1LO),因此证实Sb元素作为受主杂质掺杂已进入ZnO晶格。 |

Abstract: Sb doped large-scale ZnO nanorods were grown on Si (100) substrates by chemical vapor deposition method without using of catalyst. The X-ray diffraction (XRD) indicates the product has the hexagonal wurtzite ZnO structure. The energy-dispersive X-ray spectroscopy (EDS) was used to investigate the elemental composition in the Sb doped ZnO nanorods. The Sb related acceptor emission (A0X, FA, DAP, and DAP-1LO) was observed in the photoluminescence spectra at 11 K for Sb doped ZnO samples. This suggested that Sb related acceptor was existed in the ZnO nanorods. |
