| Abstract: | Broadband optical absorbers have important application value in solar energy utilization,optical detection and other technical fields.Teardrop-shaped surface nanostructured aluminum broadband absorber was prepared by vacuum electron beam evaporating combined with subsequent high temperature annealing,wet chemical etching and tape stripping using porous anodic aluminum oxide(AAO)membranes as a template in this paper.The absorbance of as-prepared teardrop-shaped Al nanostructure absorber is higher than 93%in the wavelength range of 200-980 nm and the absorption spectral bandwidth in the ultraviolet region is larger than reported single metal broadband absorbers.In addition,as prepared aluminum broadband absorber is of very good time stability due to the native oxide layer formed on its surface.The preparation approach developed in this paper can realize a high efficiency,low cost scaled fabrication of the surface nanostructured aluminum broadband absorber and provides a new way for developing the single metal broad band absorber. |
