文摘

Hierarchical SnO2@ZnO nanostructures are successfully synthesized in a large scale by using a simple hydrothermal method. The SnO2 nanowires epitaxially grow on the non-polarized plane of ZnO nanorods with a six-fold symmetry. The radar wave absorbing and infrared emissivity properties of hierarchical SnO2@ZnO nanostructures are studied. Such hybrid hierarchical SnO2@ZnO nanostructures show enhanced radar and infrared compatible stealth properties than ZnO or SnO2. The minimum reflection loss (RL) is −23.51 dB at 9.2 GHz with a bandwidth (RL<−10 dB) of 3.5 GHz and the average infrared emissivity in middle-infrared band and far-infrared band are around 0.65 and 0.89, respectively.
