| 英文摘要 | we have prepared a novel fiber-optic evanescent wave sensor (fews) for dissolved oxygen (do) detection. the sensor fabrication was based on coating a decladded portion of an optical fiber with a microporous coating, which was prepared from 3,3,3-trifluoropropyltrimethoxy-silane and n-propyltrimethoxysilane. the fluorophores were immobilized in the porous coating and excited by the evanescent wave field produced on the core surface of the optical fiber. the sensitivity of the sensor was quantified by the ratio of the fluorescence intensities in pure deoxygenated (i-0) and in pure oxygenated environments (i). results show that the quenching response of do is increased with the enhancement of the coating surface hydrophobicity using the presented hybrid fluorinated ormosils. the calibration curve of i-0/i to [o-2] is linear from 0 to 40 ppm and the detection limit is 0.05 ppm (3 sigma) with a short response time of 15 s for do detection. |
