Nano-aluminum films, nano gold films, nano 2, 5-diphenyloxazole (DPO) thin films and two-component nano-Al/DPO, Au/DPO composite laminated films were fabricated by DC sputtering method and vacuum deposition method. The electrochemical properties, fluorescence properties and surface morphology of the films were characterized by four-point probe resistance tester, fluorescence spectrophotometer and scanning electron microscopy (SEM), respectively. In the solid photoluminescence spectra of the Au/DPO and Al/DPO laminated composite film, a significant red shift of fluorsence emission peak occurred. The interaction within Au/DPO laminated composite films was weaker than in the single-component DPO nanofilm samples, while the Al/DPO laminated composite nano films have strong interaction, and the figure of the spectral line altered tremendously. The full width at half maximum (FWHW) of Al/DPO composite film is significantly increased. It is presumed that there is a discrete energy level structure in the particles.
