利用化学溶液沉积法,以Zn(CH_3COO)_2.2H_2O、六次甲基四胺为原料制备了规整而有序的ZnO纳米棒阵列。用FESEM、XRD等考察种子液浓度、反应溶液浓度等对ZnO纳米棒表面形貌、晶粒大小及晶体结构的影响。结果表明,制备的ZnO纳米棒的直径随反应溶液浓度增大而增大,纳米棒垂直于基底沿着(002)面生长。紫外可见吸收光谱表明,ZnO纳米棒对300~400 nm波长范围的光有很强吸收性;在500~700 nm有一个相对比较弱的吸收峰,光致发光谱图中在384 nm处有一个近紫外带边发射峰。 |

Ordered ZnO nanorod arrays were fabricated by chemical bath deposition method using Zn(CH_3COO)_2·2H_2O and C_6H_(20)N)4 as precursors.The influence of the deposition condition,such as the concentrations of reaction and seed solution,on the morphology,grain size and crystal structure of ZnO nanorod,were investigated by FESEM and XRD.The results indicate that the diameter of ZnO nanorods increases with the increase of concentration of reaction solution.The nanorods grows perpendicularly to the substrate along the(002) crystal facets.UV-Vis spectrum of ZnO nano-rods arrays show an intense absorption at 300-400 nm wavelength and a weak absorption in 500-700 nm wavelength range.The dominant UV band emission of ZnO was observed at approximately 384 nm wave length. |
