Abstract

The invention provides a fluorescence sensor for detecting the steam of chemical substances. The fluorescence sensor comprises an exciting light element, a tubular detection cavity, a detection layerand a fluorescence receiving element, wherein the inner wall of the tubular detection cavity is coated with the detection layer; the exciting light element, is used for irradiating along the axial direction of the tubular detection cavity; the tubular detection cavity is coated with the detection layer and is used for limiting the gas flow direction of a detected substance; the detection layer reacts with the detected substance to change the strength or a spectrum of fluorescence excited by the exciting light element; and the fluorescence receiving element is used for receiving light beams influenced by the reaction of the detection layer and the detected substance and determining whether the strength or the spectrum of the fluorescence of the light beams changes. The detection layer of the fluorescence sensor is prepared from sensitive fluorescence micromolecule nanomaterial with a three-dimensional porous structure, so that the utilizaitonrate of the detected substance is increased,and the coherence and reliability of detection results are guaranteed.

Description

technical field [0001] The invention relates to the technical field of substance detection, in particular to a fluorescence sensor. Background technique [0002] Fluorescence sensor is a new type of chemical sensor that has emerged in recent years. This sensor is usually built with sensitive fluorescent sensor materials, which interact with the detected substance to change the inherent fluorescence intensity or spectral composition. The fluorescent material itself has very high sensitivity. For standardized instrument detection, only by ensuring that the sensor material contacts the detected substance efficiently, uniformly and controllably can the sensor designed based on the fluorescence principle reflect the high sensitivity and high sensitivity of the material used. reliability. [0003] Most of the existing products adopt a planar fluorescence detection structure. When using this structure, the cross-section of the detection airflow needs to be the same as the macrosco...
