摘　　要：利用二次阳极氧化法制备多孔氧化铝模板,并在该模板中合成Cu纳米线。测量样品的透射光谱和偏振光谱,实验发现:这种多孔铝模板在近红外光区的透射率达到90%,可以作为近红外偏振器件的模板;含金属Cu纳米线的多孔铝膜在近红外光区具有较高的透射率和较好的偏振性能,实验中得到了样品在此区间的消光比为26dB。Porous anodic alumina templates were fabricated by the two- step anodic oxidation processes, and then Cu nanowires were synthesized in the templates. The transmission spectrum and the polarization spectrum of the samples were measured. The results show that this PAA films have better transmittance,reaching 90% in the near infrared region, hence, it can be taken as a template of polarizer in the near infrared region. The porous alumina films with Cu nanowires have better transmittance in the near infrared re...
