ABSTRACT:
In a sensor element for determining the O.sub.2 content of a sample, comprising a fluorescent indicator substance which is embedded in a polymer carrier and with which the sample may be brought into contact, a fluorescence extinction sufficiently high for yielding useful measurement results is achieved by the use of plasticizer-compatible polymers as carrier materials which contain plasticizers in addition to the indicator molecules.
