| 微纳光纤与其他微纳结构的集成可以拓展荧光光纤传感器检测范围和集成度,是光纤传感领域的研究热点。目前,国际上关于荧光光纤传感器这一领域的研究还处于单一检测物荧光响应的阶段,对多检测物的多通道荧光响应仍存在很大挑战。本文结合微纳光纤的光波导性能以及有机荧光材料的光功能特性,制备了能够同时激发和收集多种荧光的微纳光纤,并将之应用于高性能荧光光纤传感器的制备。通过选用不同荧光波长的有机材料与凝胶掺杂,制备了多荧光发射的光纤涂层材料,可控构筑了多组分荧光检测剂掺杂凝胶涂层。利用荧光光谱结合色度图分析,确定检测物与色坐标的关系,实现了多检测物的多通道荧光响应,为实现多荧光光纤传感器的可控构筑提供了有益的借鉴和指导意义。 |

| Integration of micro-nano fiber with other micro-nano structures can expand the detection range and integration of fluorescent optical fiber sensors, which is a research hotspot in the field of optical fiber sensing. At present, international research on fluorescence optical fiber sensors is still at the stage of single-detector fluorescence response, and there are still great challenges for multi-detector multi-channel fluorescence response. This dissertation combined the optical waveguide properties of micro-nano optical fibers and the optical functional properties of organic fluorescent materials to fabricate micro-nano optical fibers that can simultaneously excite and collect fluorescence, and apply them to the fabrication high-performance fluorescent optical fiber sensors. Different organic opto-functional materials with varying wavelengths were chosen and doped into the gel to construct a multi-emission fluorescent coating, which proposed a controllable fabrication strategy for constructing multi-component fluorescent detector doped gel coating. Using fluorescence spectroscopy combined with chromaticity map analysis to determine the relationship between detectors and color coordinates, the multi-channel fluorescence response for multiple detectors was achieved, which provided useful reference and guidance for the realization of controllable construction of multi-fluorescent optical fiber sensors. |
