面向物联网应用的高灵敏高分辨快响应的光纤荧光传感器件研究

Focusing on the present disadvantage of fluorescent sensor on the sensitivity, resolution, response time, size, and in-situ real time features, this proposal intends to carry out deep research from three lays, i.e. materials, device and application. From the view of materials, the lanthanide metal-organic frameworks, which can inhibit luminescent self-quenching effect and enlarge acting area between luminescent detection material and analyte, are proposed and studied. The luminescent detecting materials system, which owns the merits of highly sensitive, fine resolution and fast response, are built and acquired. From the view of device, the recombination of luminescent detecting material and glass body is explored, and the microstructure composite fiber is fabricated, which can enhance the three interaction among laser filed, luminescent detecting materials and analyte. From the view of application, based on the luminescent material composite microstructure fiber, the fluorescent sensors with features of high integration, highly sensitive, fine resolution, fast response, multi-parameter, in-situ real time, small size and low power consumption are deeply explored and functional realized. High performance fiber fluorescent sensors for various analyte detecting, such as temperature, humidity, oxygen, trace explosives, heavy metal ions and so on, are fully developed and demonstrated.
