摘要
用金属醇盐水解法在阳极Al2 O3模板的有序孔洞中生长了纳米量级的ZnO颗粒 ,并用扫描电子显微镜 (SEM )和高分辨电子显微镜 (HRTEM )对其形貌进行观察。对纳米ZnO/多孔阳极Al2 O3模板组装体的光致发光谱进行测量 ,将组装体中纳米ZnO颗粒的发光强度与常规方法制备的纳米ZnO颗粒发光强度做了比较 ,就发光强度提高的原因进行了讨论。
Nano-ZnO particles were prepared in the ordered pores of anodic aluminum oxide membranes through hydrolyzation routes of metal alkoxide. Scanning Electron Microscope (SEM) and High Resolution Transmission Electron Microscope (HRTEM) were used to observe the morphology. Photoluminescence spectra of the assembly of nano-ZnO/anodic aluminum oxide membrane were measured. The photoluminescence intensity of the nano-ZnO particles in the assembly was compared with that of nano-ZnO particles which was prepared by conventional process. The reason of the enhancement of the photoluminescence intensity was discussed.
