中文摘要: |
多功能化是光纤化学传感器的重要发展方向。为实现该目标,首先通过激光诱导波导自形成技术制备了一种光纤–水凝胶聚合物波导–光纤传感结构,并在水凝胶聚合物波导探针中成功地掺杂了纳米金颗粒。在该结构中,波导与光纤同轴无缝相连,保证了探测光和信号光的高效利用。掺金后的聚合物波导具有丰富的光谱探测能力,利用该波导探针成功实现了对盐酸吖啶黄的吸收、荧光以及拉曼光谱的检测,扩大了波导传感器的应用范围。 |

Multi-functionalization is an important development direction of optical fiber chemosensors. A laser-induced self-written waveguide technique is used to prepare optical fiber-hydrogel polymer waveguide-fiber sensing structures. In this structure, the waveguide is coaxially connected to the optical fibers, which ensures the high efficiency of pumping light launching and signal collection. In order to broaden the sensing abilities of the optical fiber-polymer waveguide-fiber (OFWF) sensor, gold nano-particles (AuNPs) are successfully doped into the waveguide session of the OFWF. The AuNPs-doped OFWF sensor is good at spectral detection. We successfully achieved the absorption, fluorescence and Raman spectra measurement of acriflavine hydrochloride. It is believed that the AuNPs-doped OFWF has great potential in various applications. |
