Comparison on Optical Properties of Cu-Al₂O₃ and Co-Al₂O₃ Nano-Array Composite Structure

Abstract:

Cu-Al₂O₃ (Co-Al₂O₃) nano-array composite structures assemblies with Cu (Co) grown in the pores of an anodic alumina membrane (AAM) were obtained by alternating current electrode position. Their transmitted spectra and polarized spectra are systematically investigated. Experimental results indicate that the transmittance of Cu-Al₂O₃ is superior to that of Co-Al₂O₃ in visible and infrared waveband, but the extinction ratio of Co-Al₂O₃ is better than that of Cu-Al₂O₃ in near infrared waveband.
