以硝酸锌、氨水为原料,采用低温水浴法在不同的温度下大规模制备了团簇状ZnO纳米棒,采用扫描电子显微镜(SEM)、能谱分析(EDX)、X射线衍射(XRD)、室温光致发光(PL)等手段对ZnO纳米棒进行了表征.SEM结果表明,环境温度对ZnO的形貌和性质有很大的影响,随着温度增加,ZnO长径比越来越大,当温度为90℃时ZnO的平均直径100 nm,长度约为5 μm;EDX和XRD图谱表明,ZnO纳米棒是高纯的六角纤锌矿结构;对90℃条件下制备的ZnO进行光致发光性能测试,观察到波长位于423 nm附近有较强的蓝光发射.

Large-scale cluster-like ZnO nanorods were synthesized with material of zinc nitrate and ammonia under different temperature conditions and characterized by scan electron microscope (SEM), X-ray diffraction (XRD), and photoluminescence (PL), respectively. SEM spectra reveals that ZnO morphologies are significantly impacted by environmental temperature. With the increasing of temperature, the aspect ratio increased. The average diameter of ZnO nanorods is 100 nm, and length is about 5 μm at 90℃. EDX and XRD results indicate that ZnO nanorods are highly pure hexagonal wurtzite structure. PL spectrum shows that there is strong blue emitting light at about 423 nm area when the temperature is 90℃.
