Abstract
In this article, the anodic aluminum oxide (AAO) was prepared by two-step anodizing process in oxalic acid electrolyte. And a blue-emission of AAO itself attributed to the oxalate was observed. The AAO membrane with ordered nano-sized porous structure was an important membrane to produce nano-materials. And luminescent nano-particles embedded in AAO, such as ZnO in this article, possessed notably special performances which were due to the quantum size effect and the special environment provided by the nano-pores. Since AAO membranes possessed a unique structure, in this paper, an assumption about the application of the membrane in field emission display (FED) and electroluminescence (EL) was proposed.
