The structure of porous alumina template and properties of optical polarization of Co nanowire arrays are studied with the help of the scanning electron microscope, X ray diffraction and infrared spectroscopy. The results showed that Co nanowire arrays have an excellent polarization property in near infrared region in 2700nm. We also found that the properties of optical polarization can also be controlled by adulterating kinds of electrodepositing metal and its alloys, by controlling length of nanowire, and by changing incidence angle.展开更多
