Abstract

In recent years

there has been increasing interest in the fabrication of the ordered fine structure using the naturally occurring self-ordered structures because of their potential utilization in the development of micromechanical

electronic and optoelectronic devices. The porous anodic alumina (PAA) formed by electrochemical oxidation has a fine structure with a nanohole array

and the radius of the pores can be controlled in the range of 1.5 to 500 nm by changing the preparation conditions. The PAA has recently attracted increasing attention as a host by introducing a guest.In this paper

Cu was implanted into the pores of PAA by means of electroplating

and the Cu/PAA film was obtained. With such metallic array

the alumina films exhibit optical polarization properties. The experiment results indicated that the polarization properties of Cu/PAA film depend on electroplating conditions. To a certain extent

with the increase of electroplating time and current density

the extinction ratio of Cu/PAA film can be improved; the temperature of electroplating solution is an important factor to influence on the extinction ratio

because a higher extinction ratio can be obtained at a smaller density and a higher temperature. So

a micro-polarizer can be achieved by optimizing electroplating conditions. With the simple technique

the controlled size and the convenience for industrialization

the Cu/PAA film prepared by electrochemical oxidation has extensive prospects in optical telecommunication.
