摘　　要：荧光式传感技术是一种跨多个学科的新型传感技术,目前非光物理量的荧光式传感器研究多处于起步阶段。结合实验室在荧光式传感方法及应用方面开展的研究,从温度、力、位移、湿度等参量角度,解释了荧光式传感原理;讨论了荧光寿命、荧光强度猝灭、荧光强度比、荧光谱移动、荧光混色法等多种荧光式传感方法及其典型传感特性,指出荧光寿命式、荧光强度猝灭式技术二者的基础物理效应相同;介绍了荧光光谱数据的处理方式方法,其中重点介绍了表征谱带轮廓整体频移的新型参量"谱带重心"的定义,以及该参量如何在不改变光谱仪器硬件条件的前提下提高传感精度;最后对荧光式传感技术的发展方向和应用前景提出了思考。Fluorescence-based sensing technology belongs to the multidiscipline fusion of sensors and transducers.Especially,research on physical quantity is in the start-up stage.The principles and methods of fluorescence temperature-/force-/displacement-/humidity-sensing techniques are introducted.And some examples are illustrated,including our researches.Fluorescence lifetime,fluorescence intensity quenching,fluorescence intensity ratio,fluorescence spectral shift,and fluorescence colormetric analysis processes are discussed.The typical sensing properties are compared with other techniques.A particular note is that fluorescence lifetime is the other side of fluorescence intensity quenching.Data processing is introduced,which focuses on how to improve the sensing precision with a novel spectral characteristic,named as"emission band barycenter".At the end,the future development and applications are provided.
