摘要: The fabrication and characterization of an optical fiber oxygen sensor based on fluorescence quenching are described. sensors prepared by coating the sensitive indicator (tris-BP ruthenium (II) chloride platinum octaethylporphyrin) that is immobilized sol-gel route onto uncladded middle portion a multimode plastic fiber. A design experiment two parameters which coated length withdrawal rate was carried out in order to identify optimum setting gives highest emission leads better sensitivity. sensitivity quantified terms ratio I 0 /I where Irepresent intensities pure nitrogen environments, respectively. Both produced linear Stern-Volmer relationship indicate homogeneous environment luminophore. experimental result reveals optimized for 5 mm decladded 120 mm/min while 8 160 rate.
