(57) [Summary] (Modified) [Problem] To bring out the emission characteristics of a measured substance, it has a high degree of transparency and sufficient permeability of the measured substance, and has both mechanical and chemical durability. An optical sensor is provided. An optical sensor for measuring a target substance, particularly for measuring oxygen, comprises a sensor matrix substantially made of a fluoropolymer. The sensor matrix is composed of a metal complex of ruthenium, rhenium, rhodium or iridium and a luminescent indicator comprising at least one at least partially fluorinated ligand. |
