| 摘 要： | 采用化学溶液沉积法在ITO导电玻璃上制备近一维ZnO纳米棒. 利用X射线衍射（XRD) 、扫描电子显微镜（SEM）和光致发光谱（PL）对样品进行表征，研究了不同Zn2+摩尔浓度和不同生长时间对样品的结构、形貌和光致发光性能的影响. 结果表明，所制备的ZnO纳米棒为纤锌矿结构并沿c轴择优取向生长. 另外，随着Zn2+摩尔浓度的增加，纳米棒的直径增大. 当Zn2+摩尔浓度为0.1M时，ZnO纳米棒的直径和长度都随生长时间的增加而增加. PL测试表明，样品均具有良好的发光性能，并且ZnO纳米棒的结晶质量随着Zn2+摩尔浓度和生长时间的增加均有所提高.

| Abstract: | Zinc oxide (ZnO) nanorods are grown on ITO conducting glass with the chemical bath deposition (CBD) method.XRD,SEM,and PL are used to characterize the crystal structures,surface morphologies,and photoluminescence properties of ZnO nanorods.The X-ray measurement results show that the growth orientation of the as-prepared ZnO nanorods is (002).The SEM results show that the size of ZnO nanorods increases with the molar concentration of zinc nitrate,and the diameter and length of nanorods increases significantly through tuning the reaction time when the molar concentration is 0.1M.The photoluminescence measurements show that the all the samples have good photoluminescence behaviors.The crystallization of the samples increases with the molar concentration of zinc nitrate and the reaction time. |
