Abstract

An optical sensor for determining an analyte, specifically oxygen, has a sensor matrix that is made up substantially of a fluoropolymer. The sensor matrix contains a luminescent indicator with a metal complex of ruthenium, rhenium, rhodium or iridium, and with at least one at least partially fluorinated ligand.
