| 英文摘要 | a fiber-optic sensor based on fluorescence quenching was designed for dissolved oxygen (do) detection. the fluorinated xerogel-based sensing film of the present sensor was prepared from 3, 3, 3-trifluoropropyltrimethoxysilane (tfp-trimos). oxygen-sensitive fluorophores of tris (2, 2'- bipyridine) ruthenium (ii) (ru(bpy) (3) (2+) ) were immobilized in the sensing film and the emission fluorescence was quenched by dissolved oxygen. in the sensor fabrication, a two-fiber probe was employed to obtain the best fluorescence collection efficiency and the sensing film was attached to the probe end. scanning electron microscope (sem), uv-vis absorption spectroscopy (uv-vis) and fourier transform infrared spectroscopy (ftir) measurements have been used to characterize the sensing film. the sensor sensitivity is quantified by i (deoxy)/i (oxy), where i (deoxy) and i (oxy) represented the detected fluorescence intensities in fully deoxygenated and fully oxygenated environments, respectively. compared with tetramethoxysilane (tmos) and methyltriethoxysilane (mtms)-derived sensing films, tfp-trimos-based sensor exhibited excellent performances in dissolved oxygen detection with short response time of 4 s, low limit of detection (lod) of 0.04 ppm (r.s.d. = 2.5%), linear stern-volmer calibration plot from 0 to 40 ppm and long-term stability during the past 10 months. the reasons for the preferable performances of tfp-trimos-based sensing film were discussed. |
