Abstract
An oxygen-sensitive luminescent element, and probe constructed therefrom, having reduced cross-sensitivity to humidity, and methods of manufacturing and using such luminescent elements and probes to measure oxygen concentrations within an enclosed space. The luminescent element includes a glass fiber carrier substrate bearing an oxygen-sensitive photoluminescent dye. The dye is preferably embedded within an oxygen-permeable hydrophobic polymer matrix. A probe is constructed from the luminescent element by laminating the luminescent element onto a structural support layer.
