title = "Highly-sensitive optical fiber oxygen sensor based on dye entrapped core-shell silica nanoparticles",
abstract = "This paper presents a highly-sensitive oxygen sensor that comprises an optical fiber coated at one end with platinum (II) meso-tetrakis (pentrafluorophenyl)porphine (PtTFPP) and PtTFPP entrapped core-shell silica nanaparticles embedded in an n-octyltriethoxysilane (Octyl-triEOS)/ tetraethylorthosilane (TEOS) composite xerogel. The sensitivity of the optical oxygen sensor is quantified in terms of the ratio I0/I100, where I0 and I100 represent the detected fluorescence intensities in pure nitrogen and pure oxygen environments, respectively. The experimental results reveal that the oxygen sensor has a sensitivity of 166. The response time was 1.3 s when switching from pure nitrogen to pure oxygen, and 18.6 s when switching in the reverse direction.",
