摘　　要：The porous alumina have been prepared by anodization and an organic molecule 8-hydroxyquinoline aluminum (Alq3) has been impregnated in the pores. The morphology measured through atomic force microscopy shows that the size of the pores is about 10 nm. A blue-shift photoluminescence of Alq3 in nanometer-sized hole is close to that of the monomers. The measured spectral characteristics demonstrate the limitation of the porous alumina to the emission of Alq3.The porous alumina have been prepared by anodization and an organic molecule 8-hydroxyquinoline aluminum (Alq3) has been impregnated in the pores.
