| 摘 要： | 采用的两步法——先溅射成膜,后退火处理的工艺成功制备了ZnO:Tb复合薄膜,结合XRD、SEM、PL等手段研究了掺杂量对薄膜结构和形貌的影响.发现掺杂量为4.16%时,ZnO:Tb薄膜表面形成新奇T-A-ZnO结构以及不同直径和长度的螺纹状纳米棒;同时出现378 nm和387 nm两个较强的紫外发光峰,以及中心波长位于515 nm的强绿光峰.

| Abstract: | A two steps route to obtain 3D ZnO structures by annealing treatment of the sputtered ZnO∶Tb thin films was report.The influence of dopant content on the structure and morphology of ZnO∶Tb thin films on Si substrate was investigated.And we found that a special tetrapod-aiguille-ZnO structure(T-A-ZnO)together with screw-like nanorods has been formed on ZnO∶Tb thin films with.4.16 % Tb dopant..The PL spectrum of the film with the special structure is featured with two UV emission peaks(at 378 and 387 nm)and a strong green emission band(centered at 515 nm). |
