英文摘要absorption, room temperature PL spectra and Raman spectra were measured for the product synthesized by changing the contents of AgNO3, . The results showed that, the bandgap of ZnO narrowed because of doping. Near band emission intensity of room temperature PL spectra also decreased and shifted to red, while the visible light emission intensity gradually increased with the increase of AgNO3. Raman scattering frequency shifted toward the low frequency with the increasing of the dopant content linearly. We discussed and explained these phenomena.Keywords: ZnO; Doping; Chemical vapor deposition目录中文摘要 ...........................................................IAbstract ..........................................................II目录..........................................................IV第一章 绪论.........................................................11.1 ZnO 纳米材料的基本性质1ZnO 的晶体结构1ZnO 的本征缺陷2ZnO 的光学性质4ZnO 的电学性质61.2 ZnO 掺杂的研究现状61.3 ZnO 纳米材料的制备与表征81.3.1 ZnO 纳米材料的制备81.3.2 纳米 ZnO 的表征91.3.2.1 扫描电子显微镜（SEM）91.3.2.2 透射电子显微镜（TEM） 101.3.2.3 X 射线衍射分析（XRD） 101.3.2.4 荧光光谱仪 ......................................111.3.2.5 拉曼光谱仪(Raman) 111.3.3 本论文的实验方法与设备................................121.4 本论文的研究意义及内容 .....................................14参考文献 .......................................................15第二章 Cu 掺杂 ZnO 纳米材料的制备及光学性能172.1 引言 .......................................................172.2 实验过程 ...................................................172.3 方式一的实验结果与分析 .....................................182.3.1 形貌分析 ..............................................182.3.2 XRD 和 EDS 分析202.3.3 光致发光(PL)分析 222.4 Cu 掺杂 ZnO 阵列的光学性能及其可控制备 232.4.1 Cu 掺杂 ZnO 阵列的光学性能分析 232.4.2 Cu 掺杂 ZnO 阵列的可控制备 262.5 小结 .......................................................29参考文献 .......................................................30第三章 Ag 掺杂 ZnO 纳米材料的制备及光学性能 323.1 引言 .......................................................323.2 实验过程 .....................................
