An optical sensor is proposed for determining gases in gas mixtures, especially for determining one gas component in the air, having a sensitive layer exposed to the gas and having a device for detecting a change in an optical property of the sensitive layer. The sensitive layer of the sensor contains a phosphorus or nitrogen-containing base having numerous and/or long-chain alkyl groups for the pH adjustment of the sensitive layer.

Optical sensor

An optical sensor is described for determining the concentration of a gas in gas mixtures, which can especially be used for determining the carbon monoxide content of the air. It includes a radiation source, a sensitive layer positioned on a translucent substrate, and a detector. The sensitive layer of the sensor contains a transition metal compound which forms a transition metal complex with the gas to be determined.
