Optical oxygen sensors generally function based on incorporation of a phosphorescent molecule, such as a transition metal polypyridyl complex or heavy metal porphyrin, into a polymer matrix (e.g., thin film, electrospun fibers, etc.). The long-lived luminescence from the incorporated molecule is dynamically quenched in the presence of oxygen. Considering the phosphorescence quantum yield in the presence or absence of oxygen .
