| 摘 要： | 为优化激光干涉诱导向后转移（laser-interference-induced backward transfer，LIIBT）技术制备微纳结构工艺参数，研究了激光脉冲数和激光能量密度对LIIBT技术的影响。以钠钙玻璃为接收衬底，金薄膜为靶材，在大气环境下进行双光束LIIBT实验验证。实验结果表明，随着激光脉冲数和激光能量密度增加，金微纳条纹的分辨率有明显提高。能谱仪（energy dispersive spectrometer，EDS）分析结果表明，在金微纳条纹结构上，Au元素随激光脉冲数的增加聚集在条纹区域。利用不同浓度的罗丹明B溶液作为探针分子进行拉曼光谱研究，发现了金微纳条纹结构对罗丹明B的表面增强拉曼散射（surface-enhanced Raman scattering，SERS）效应。总之，LIIBT为拉曼光谱测试低浓度有害物质提供一种便携、廉价的金属拉曼增强衬底。 |

| Abstract： | In order to optimize the laser-interference-induced backward transfer (LIIBT) process parameters for preparing micro-nano structures, the influence of laser pulse number and laser fluence on LIIBT was studied in this paper. Using sodium-calcium glass as the receiving substrate and Au film as the target, the double-beam LIIBT experiment was carried out in an atmospheric environment. The experimental results showed that as the laser pulse number and laser fluence increase, the resolution of Au micro-nano stripe was significantly improved. The energy dispersive spectrometer (EDS) analysis results indicated that in the Au micro-nano stripe structure, the Au elements gathered in the stripe area with the increase of the laser pulse number. Using rhodamine B solution with different concentrations as probe molecules for Raman spectroscopy, 6 characteristic peaks were found, which proved the surface-enhanced Raman scattering (SERS) effect of the Au micro-nano stripe structure on rhodamine B. The study demonstrates that LIIBT provides a simple and cheap metal Raman-enhanced substrate for Raman spectroscopy testing of low-concentration harmful substances. |
