“…6) can be described by the linear Stern-Volmer equation. Over all, Table 2 compares the performance characteristics of the representative quenchometric O 2 sensors presented in the literature comprising PtTFPP, PtOEP or Ru(dpp) 3 2+ dyes embedded in various support matrices. Comparing the performance of various sensors, it is apparent that sensors that use a platinum (II) complex as the sensing dye [16,17,25] have a significantly higher sensitivity than those using Ru(dpp) 3 2+ dye [6,7,29].…”

“…Consequently, considerable efforts have been spent over years in developing suitable techniques for the measurement of O 2 concentrations. Fluorescent optical oxygen sensors overcome the limitations of conventional Clark electrode and are widely applied throughout chemical [1], clinical [2] and environmental monitoring [3] fields. Optical oxygen sensors consist of an oxygen-sensitive dye entrapped in a matrix with a high permeability to oxygen.…”

Oxygen and carbon dioxide sensors are involved in many chemical and biochemical reactions. Consequently, considerable efforts over years have been devoted to discover and improve suitable techniques for measuring gas concentrations by optical fiber sensors. Optical gas sensors consist of a gas-sensitive dye entrapped in a matrix with a high permeability to gas. With such sensors, gas concentration is evaluated based upon the reduction in luminescence intensity caused by gas quenching of the emitting state. However, the luminescence quenching effect of oxygen is highly sensitive to temperature. Thus, a simple, low-cost plastic optical fiber sensor for dual sensing of temperature and oxygen is presented. Also, a modified Stern-Volmer model is introduced to compensate for the temperature drift while the temperature is obtained by above dual sensor. Recently, we presented highly-sensitive oxygen and dissolved oxygen sensors comprising an optical fiber coated at one end with platinum (II) meso-tetrakis(pentafluorophenyl)porphyrin (PtTFPP) and PtTFPP entrapped core-shell silica nanoparticles embedded in an n-octyltriethoxysilane(Octyl-triEOS)/tetraethylorthosilane (TEOS) composite xerogel. Also, two-dimensional gas measurement for the distribution of chemical parameters in non-homogeneous samples is developed and is of interest in medical and biological researches.

“…Although this sensor provides reasonably accurate measurement results, it has a number of drawbacks which limit its general applicability, most notably high oxygen consumption, a slow response time, poor reliability, and questionable safety [2]. Optical oxygen sensors effectively remove many of these limitations and have therefore found widespread use in chemical [3][4][5][6][7][8], clinical [9,10], and environmental [11] fields. Such sensors detect the oxygen concentration by monitoring the reduction in the fluorescence intensity of an excited fluorescent indicator as a result of the quenching effect induced by the oxygen environment.…”

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 I 0 /I 100 , where I 0 and I 100 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.
