Porous anodic aluminum oxide prepared by electrochemical method has a uniform pore size, parallel to each other, the arrangement of regular microporous structure can be used as a transparent substrate for a variety of light-emitting materials with porous aluminum as a carrier, the organic dye embedded in porous aluminum, The solid inlaid films of organic dyes were obtained and the absorption spectra and photoluminescence spectra of the inlaid films were measured.The absorption spectra of the inlaid films were basically the same as those of liquid dyes.The blue light emission peaks of the photoluminescence spectra were blue shifted and the luminescence intensity decreased, But the spectral line tends to be more symmetrical.The experimental results show that the dye exists in the form of monomer in the porous aluminum.After a series of post-treatment on the porous aluminum substrate, it was found that heat treatment and expansion of porous aluminum porosity can enhance the luminescent intensity
