Studies on Intense Photoluminescence of Nano-ZnO Particles in Anodic Aluminum Oxide Membrane

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.
