The photothermal conversion property of Au-CuS composites based on butterfly wings in the near-infrared region

以裳凤蝶前翅(T_FW)为模板,通过化学合成方法制备了具有三维减反射准周期性微纳结构的金属/半导体(Au-CuS_T_FW)功能材料以研究其近红外光热转换性能。通过XRD检测了复合材料的表面成分组成;通过超景深光学显微镜和扫描电子显微镜观察了原始蝶翅以及复合功能材料的表面形貌以及横截面;通过透射电子显微镜的低分辨、高分辨以及选取电子衍射观察了复合材料的表面形貌、晶面间距。通过设计实验,得到该复合材料、金"蝶翅"(Au_T_FW)、CuS"蝶翅"(CuS_T_FW)以及性能优异的太阳光吸收材料BlueTec eta plus_Cu的光热转换效率,并对它们进行了对比,发现该复合材料具有更优异的近红外光热转换性能。

The study investigates the photothermal conversion property of Au-CuS composites based on butterfly wings（Au-CuS_T_FW）in the near-infrared region,which is prepared by chemical synthesis method.To investigate the constituent of functional materials,XRD is used.Through using VHX and SEM,the surface and cross section of the composites and original butterfly wings are observed.Besides,by using TEM,HRTEM and SAED,the surface morphology,crystalline interplanar spacing and crystallinity of composites are observed.What＇s more,the photothermal conversion property of the composites,Au＂wings＂（Au_T_FW）and CuS＂wings＂are also obtained.By comparison,it can be concluded that the photothermal conversion property of the composites is better than the others.
