研究了不同衬底条件对纳米粒子辅助脉冲激光烧蚀沉积制备的氧化锌纳米结构的形貌、晶体结构和光致发光的影响。结果表明,蓝宝石衬底在1000℃下进行1h的热处理最有利于纳米结构的垂直生长。扫描电子显微镜分析表明,在经过处理的蓝宝石衬底上成功地合成了具有独特形状的取向良好的直径调制的氧化锌纳米棒。所合成的氧化锌纳米结构在390 nm附近有紫外光发射,在室温下没有绿光发射,表明在氧化锌晶格内部存在很低浓度的深能级缺陷。这种新颖的氧化锌纳米结构可以为基础研究和技术应用提供新的机会。
The effects of various substrate conditions on the morphology, crystal structure and photoluminescence of ZnO nanostructures synthesized by nanoparticle-assisted pulsed-laser ablation deposition were investigated. It is concluded that the sapphire substrate with a 1h anneal at 1000°C is the most favorable to the vertical growth of ZnO nanostructures. SEM analysis indicates that the well-aligned diameter-modulated ZnO nanonails with unique shape were successfully synthesized on the annealed sapphire substrate. The as-synthesized ZnO nanostructures exhibit an ultraviolet emission at around 390nm and the absent green emission under room temperature, indicating that there is a very low concentration of deep-level defects inside ZnO lattices. The novel ZnO nanostructures could offer novel opportunities for both fundamental research and technological applications.
