Abstract
Plasma resonance absorption properties of the Ag-AAO nano-array composite are studied. The spectral analysis shows that the surface plasma resonance peak of Ag occurs at λ=352∼377 nm. As the Ag composition decreases, the dipolar plasma resonance absorption peak shifts to the longer wavelength, weakened and gradually expanded, and vice versa. The theoretical analysis shows that the M-G calculated results agree well with the experimental ones.
