| In this paper, we introduced development history,physical and optical characteristics of nano materials, research actuality,structure and forming mechanism of porous anodic alumina film ,and research course,structure and emission mechanism of irradiance material.We have reported the process of forming nano ZnO luminescence material in porous anodic alumina template by sol-gel method. At last, we analyzed and discussed the testing results by kinds of test methods.We developed frondose works as follow:(1) The porous alumina film with ordered nanochannels was prepared by a two-step andozation of alumimum, using oxalic acid and phosphonic acid for electrolyte and choosing optimum parameters.(2)We prepared nano ZnO by sol-gel method and nano ZnO/PAA composit system by sediment.(3)We tokened the structure,appearance,constituts of porous anodic alumina nano ZnO and ZnO/PAA composite system and discussed optical character.(4)We studied the influence of different annealing temperature for porous anodic alumina,nano ZnO and ZnO/PAA composite system, and discussed the emission mechanism(5)We analyzed the content of nano ZnO in porous anodic alumina, and discussed the reason of influencing nano ZnO's ingress.Finally, we suggested that the experiment method should be improved for getting finer ZnO/PAA composite system. Because photoluminescence experiment belongs to property of basic research, we will develop electroluminescence research in the future so that ZnO/PAA composite system applied to practice.
