摘　　要：采用磁控溅射法和水热法在玻璃片上制备了具有较好光致发光性能的Sn-Al共掺杂ZnO纳米棒。采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)和光致发光(PL)光谱表征了样品的表面形态、晶体结构和光致发光特性。结果表明Sn掺杂促进了ZnO纳米棒的横向生长,ZnO纳米棒的直径随着Sn掺杂量的增加而增加且长度变短,结晶质量也随之下降。Sn掺杂ZnO纳米棒对紫外光区峰值强度没有明显的影响,但Sn的掺杂浓度低时会导致发光峰发生蓝移,随着Sn的掺杂浓度达到一定水平时,则观察到发光峰开始红移。在可见光区峰值强度随着Sn掺杂浓度的增加而增加。Sn-Al co-doped ZnO nanorods with better photoluminescence properties were prepared on glass sheets by magnetron sputtering and hydrothermal method.The surface morphology,crystal structure and photoluminescence properties of the samples were characterized by scanning electron microscopy(SEM),X-ray diffractometer(XRD)and photoluminescence(PL)spectra.The results show that Sn doping promoted the lateral growth of ZnO nanorods.The diameter of ZnO nanorods increased with the increase of Sn doping amount but the length became shorter.The crystallization quality also decreased.Sn doping ZnO nanorods had no obvious effect on the peak intensity in the ultraviolet region,but when the doping concentration of Sn was low,it would lead to the blue shift of the luminescence peak.As the doping concentration of the Sn reached a certain level,it was observed that the luminescence peak began to red shift.Peak intensity in the visible region increased with increasing Sn doping concentration.
