Development of ratiometric fluorescent oxygen-sensing membranes for oxygen sensors |
| 초록 |
Oxygen concentration is an important parameter in various applications. Principle of oxygen sensors are based on the dynamic luminescence quenching by molecular oxygen that is described by Stern-Volmer equation. In this study, the fluorescence quenching of Pt(II) meso-tetra(pentafluorophenyl)porphine (PtP) by oxygen molecules is exploited for fabrication of the oxygen-sensing membrane. The quantum dots (QDs) or green dye (GN) is used as a reference dye to perform ratiometric fluorescence measurements. Before the fabrication of the sensing membrane, PtP is captured in polystyrene particles (PS). GN is captured in silica particles or melamine formaldehyde resin particles. All dye particles are supported by polymer poly(styrene-co-acrylonitrile) to produce a thin oxygen-sensing membrane. The sensing membrane is sensitive with oxygen in the concentration range of 0% - 100% and fast reversibility |
