| 摘 要： | 通过对微结构聚合物光纤修饰桑色素-铝配合物掺杂的凝胶薄膜,制备了一种氟化物光纤传感探头。这种探头的结构基于微结构聚合物光纤实现,其内部具有贯穿的微孔道结构,这种微孔道结构可以作为敏感材料的载体以及微传感池。敏感层的修饰通过溶胶-凝胶过程实现,将掺有桑色素-铝的溶胶直接吸入光纤内部,可以在光纤微孔阵列中形成凝胶敏感膜。微结构光纤内部可以容纳微量液体,传感过程在微孔道内进行。基于荧光淬灭原理实现传感,氟离子对凝胶膜中桑色素-铝具有强烈的荧光淬灭作用,因此,传感探头对于不同浓度的氟离子溶液表现不同的荧光强度。在pH值为4.6的条件下,探头对于氟离子具有良好的响应,可在5～50mmol/L内传感。 |

| Abstract: | An optical fluoride probe was fabricated based on Microstructured Polymer Optical Fibers(MPOFs)modified by morin-Al complex doped silica gel films.The structure of this probe was based on microstructured polymer optical fibers with microholes and these microholes could be used as the substrate of sensing materials and minor reaction pools.The deposition of sensing layer was realized by a sol-gel process.When the sol doped with morin-Al was inhaled into the optical fiber,the sensing layer was formed on the i... |
