以商业化蝴蝶翅膀为衬底,采用真空热蒸发技术沉积银薄膜,制备银薄膜/蝶翅基底。结合X射线衍射仪(XRD)和扫描电镜(SEM)表征了银薄膜/蝶翅的微观结构及表面形貌。选择罗丹明6G(R6G)为探针分子,对不同品种蝶翅/银薄膜基底的表面增强拉曼散射(SERS)活性进行研究。半定量分析了R6G溶液浓度和银薄膜厚度对基底SERS性能的影响。分别在银薄膜/枯叶蝶和银薄膜/太阳蛾基底表面随机选取十二个不同位置,特征峰604、1349和1507 cm-1处强度的相对标准偏差值分别为5.30%、6.86%、5.58%和4.36%、3.21%、3.35%,表明银薄膜/蝶翅基底表面具有良好的均匀性。
Abstract
On the commercial butterfly wings,silver/butterfly wings substrates were prepared by depositing silver thin film with vacuum thermal evaporation method.The microstructure and surface morphology of silver/butterfly wings were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM).Rhodamine 6G(R6G) was chosen as the probing molecule,the surface-enhanced Raman scattering (SERS) activities of silver thin film on different butterfly wings were investigated.The effects of R6G aqueous solution concentrations and silver thin film thicknesses on SERS performances of the substrates were semi-quantitatively analyzed.In addition,twelve locations were randomly selected on the substrates of Kallima Inachus and Gypsy moth.The relative standard deviation values of the peak intensities of 604,1349 and 1509 cm-1were 5.30%,6.86%,5.58% and 4.36%,3.21%,3.35%,respectively,which indicated the prepared Ag/butterfly wings exhibited good uniformity.
